Lesson 5: Can I Know for Sure I’m Saved?
One of the most important questions a person can ask is:
Can I know for sure I’m saved?
This question matters deeply.
Some people are careless and assume they are saved when they have never truly repented and believed on Jesus Christ. That is dangerous.
Others truly have come to Christ, but they are troubled by fear, weakness, memories of past sin, spiritual attacks, changing emotions, or confusion about assurance. They wonder if they can ever have peace.
The Bible does not encourage false confidence.
But neither does it leave sincere believers trapped in endless uncertainty.
1 John 5:13 says:
“These things have I written unto you that believe on the name of the Son of God;
that ye may know that ye have eternal life…”
— 1 John 5:13, KJV
Notice the words:
that ye may know
God’s Word was written so believers could know they have eternal life.
Assurance is not arrogance when it rests on Jesus Christ and the Word of God.
Assurance is not saying, “I am saved because I am good.”
Assurance is not saying, “I am saved because I never struggle.”
Assurance is not saying, “I am saved because I had an emotional moment.”
Biblical assurance says:
“God has spoken. Jesus Christ saves. I am trusting Him. My hope is in Him, not in myself.”
Assurance Must Rest on God’s Word
Your assurance must not be built first on feelings.
Feelings change.
Some days you may feel close to God. Other days you may feel weak, dry, afraid, or troubled.
Some days your prayers may feel strong. Other days your heart may feel heavy.
Some days you may feel confident. Other days accusations may come against your mind.
If assurance depends on feelings, you will rise and fall constantly.
But God’s Word does not change.
John 5:24 says:
“Verily, verily, I say unto you,
He that heareth my word, and believeth on him that sent me,
hath everlasting life, and shall not come into condemnation;
but is passed from death unto life.”
— John 5:24, KJV
Jesus did not say, “He that feels saved.”
He said the one who hears His Word and believes has everlasting life.
That is strong.
Hath everlasting life.
Shall not come into condemnation.
Is passed from death unto life.
A believer’s assurance must begin with what God has said, not with what emotions are doing at the moment.
Assurance Must Rest on Jesus Christ
The foundation of assurance is not your strength.
It is Jesus Christ.
If you look mainly at yourself, you will find weakness, failure, incomplete growth, imperfect motives, and reasons to be humbled.
But if you look to Christ, you will find a perfect Saviour.
John 10:27–28 says:
“My sheep hear my voice, and I know them, and they follow me:
And I give unto them eternal life; and they shall never perish,
neither shall any man pluck them out of my hand.”
— John 10:27–28, KJV
Jesus gives eternal life.
Jesus knows His sheep.
Jesus keeps His sheep.
No man can pluck them out of His hand.
This does not mean a person should be careless about sin. Jesus said His sheep hear His voice and follow Him. But the security of the sheep is in the Shepherd.
A sheep is not safe because it is strong.
A sheep is safe because the Shepherd is faithful.
Your assurance must not be built on how impressive you are.
It must be built on who Jesus Christ is.
Assurance Is Not Based on Being Sinless
Some sincere believers struggle because they think assurance means they would never battle sin again.
But the Bible does not teach that believers become instantly sinless in this life.
1 John 1:8 says:
“If we say that we have no sin, we deceive ourselves, and the truth is not in us.”
— 1 John 1:8, KJV
That verse keeps us honest.
Believers still need cleansing, correction, confession, and growth.
A Christian should not make peace with sin. He should not defend sin. He should not continue comfortably in rebellion. But he also should not think every battle means he was never saved.
There is a difference between a person who falls and hates the sin, and a person who loves sin and refuses Christ’s rule.
There is a difference between conviction and rebellion.
There is a difference between weakness and hardness.
There is a difference between struggling against sin and settling down in sin.
A true believer may be grieved by sin because he belongs to God.
That grief itself may be evidence that God is dealing with his heart.
Beware of False Assurance
While sincere believers should not be trapped in needless fear, careless people must be warned.
Not everyone who says he is saved truly belongs to Christ.
Jesus said in Matthew 7:21:
“Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven;
but he that doeth the will of my Father which is in heaven.”
— Matthew 7:21, KJV
Those are serious words.
A person may use the right language and still be lost.
A person may say, “Lord, Lord,” and still not truly belong to Jesus Christ.
False assurance can be built on many wrong foundations:
“I prayed a prayer years ago.”
“I grew up in church.”
“I was baptized.”
“I am a good person.”
“I believe God exists.”
“My family is Christian.”
“I had an emotional experience.”
“I know Bible facts.”
“I am not as bad as others.”
None of those things are the true foundation of salvation.
The true question is:
Have you repented toward God and trusted Jesus Christ as Lord and Saviour?
Is your confidence in Christ, or in yourself?
Do you desire to follow Him, or are you using religious words while continuing in rebellion?
False assurance is deadly because it comforts people on the road to judgment.
A person should never use assurance as a cover for sin.
Assurance Is Connected to Faith in Christ
The Bible connects eternal life with believing on Jesus Christ.
John 3:36 says:
“He that believeth on the Son hath everlasting life:
and he that believeth not the Son shall not see life;
but the wrath of God abideth on him.”
— John 3:36, KJV
This verse gives both promise and warning.
The one who believes on the Son has everlasting life.
The one who does not believe remains under wrath.
So assurance begins by asking:
Am I believing on the Son?
Not merely:
Did I have a religious experience?
Did I repeat words?
Did people tell me I was saved?
Did I once feel emotional?
But:
Am I trusting Jesus Christ?
Do I believe He is the Son of God?
Do I believe He died for sins and rose again?
Am I looking to Him as my only Saviour?
Have I stopped trusting my own righteousness?
Faith is not confidence in self.
Faith is confidence in Christ.
Assurance Is Strengthened by the Witness of a Changed Life
A person is not saved by good works.
But a saved person should not remain unchanged.
2 Corinthians 5:17 says:
“Therefore if any man be in Christ, he is a new creature:
old things are passed away; behold, all things are become new.”
— 2 Corinthians 5:17, KJV
This does not mean instant maturity.
It does not mean every sinful habit disappears overnight.
It does not mean a new believer understands everything immediately.
But it does mean salvation is real.
God begins a work in His people.
There should be a new direction.
A new attitude toward sin.
A new desire for God.
A new hunger for truth.
A new conviction when wrong is done.
A new willingness to be corrected.
A new desire to obey Jesus Christ.
The witness of a changed life does not replace faith in Christ, but it supports assurance.
If someone says he has faith but has no concern for Christ, no conviction of sin, no desire for truth, no interest in obedience, and no fruit of grace, he should not comfort himself with empty words.
But if you see God changing your heart, convicting you, drawing you to His Word, making sin hateful, and giving you desire to follow Christ, do not ignore that work of grace.
Assurance Is Helped by Love for the Brethren
The Bible gives marks that accompany spiritual life.
1 John 3:14 says:
“We know that we have passed from death unto life, because we love the brethren…”
— 1 John 3:14, KJV
Love for the brethren is one evidence of new life.
Before salvation, a person may have little concern for God’s people. But when God saves someone, He begins changing his affections.
He begins to love what God loves.
He begins to care about believers.
He begins to desire fellowship with those who follow Christ.
This does not mean every believer has the same personality. It does not mean Christians never struggle in relationships. It does not mean love is always mature immediately.
But a saved person should not hate the people of God or despise fellowship with them.
God places love in the heart.
This love may need to grow, but its presence is a sign of life.
Assurance Is Helped by Obedience
Obedience does not earn salvation.
But obedience is one mark of truly knowing Christ.
1 John 2:3 says:
“And hereby we do know that we know him, if we keep his commandments.”
— 1 John 2:3, KJV
This verse does not say we know Him because we are sinlessly perfect.
It says there is a real relationship between knowing Christ and keeping His commandments.
A person who has no desire to obey Jesus should not claim strong assurance.
If someone says, “I know Him,” but refuses His authority, rejects His Word, and loves rebellion, he is deceiving himself.
But a sincere believer may ask:
“Do I want to obey Christ?”
“Do I grieve when I disobey?”
“Do I desire to be corrected?”
“Do I want my life to please the Lord?”
“Do I return when He convicts me?”
Those are signs of spiritual life.
Again, obedience is not the root of salvation.
Christ is the root.
But obedience is fruit that grows from true faith.
Assurance Is Helped by the Spirit’s Witness
The Holy Ghost bears witness with the believer.
Romans 8:16 says:
“The Spirit itself beareth witness with our spirit,
that we are the children of God:”
— Romans 8:16, KJV
This is a precious truth.
Assurance is not merely a human argument. God comforts His people by His Spirit.
The Spirit points us to Christ.
The Spirit convicts us of sin.
The Spirit teaches us to cry to God.
The Spirit gives desire for holiness.
The Spirit leads us in truth.
The Spirit bears witness that we belong to God.
This does not mean every believer feels the same level of comfort at all times. Some believers are more easily troubled. Some are young in faith. Some battle fear. Some have been taught confusing things. Some are under spiritual attack.
But God is able to give assurance by His Spirit as the believer looks to Christ and walks in truth.
Do not seek assurance apart from the Spirit of God.
Ask Him to bear witness through the Word and within your heart.
Doubt Does Not Always Mean You Are Lost
Some people think that if they ever doubt, they must not be saved.
That is not always true.
Doubt can come from many places.
A lack of Bible knowledge.
A tender conscience.
Spiritual attack.
Unconfessed sin.
Weakness.
Fear.
Bad teaching.
Looking too much at self.
Comparing yourself with others.
Expecting feelings to stay the same.
Doubt should not be ignored, but it should be handled biblically.
If you doubt, do not merely sit in fear.
Go to the Word.
Look to Christ.
Examine whether your faith is truly in Him.
Confess any known sin.
Ask God for light.
Seek faithful counsel if needed.
Mark 9:24 records the cry:
“Lord, I believe; help thou mine unbelief.”
— Mark 9:24, KJV
That is an honest prayer.
A struggling believer should not pretend.
He should bring his struggle to the Lord.
Hidden Sin Can Weaken Assurance
Sometimes assurance is weakened because a person is hiding sin.
A believer cannot walk in darkness and enjoy clear fellowship with God.
Psalm 32:3–4 says:
“When I kept silence, my bones waxed old through my roaring all the day long.
For day and night thy hand was heavy upon me…”
— Psalm 32:3–4, KJV
David described the misery of hidden sin.
Sin clouds the conscience.
Sin grieves the heart.
Sin makes prayer harder.
Sin makes Scripture uncomfortable.
Sin gives room for accusation.
If you are hiding sin, do not expect strong assurance while refusing confession.
Come into the light.
Psalm 32:5 says:
“I acknowledged my sin unto thee, and mine iniquity have I not hid…
and thou forgavest the iniquity of my sin. Selah.”
— Psalm 32:5, KJV
Assurance is helped when the heart is honest before God.
Do not hide what God is calling you to confess.
Assurance Should Produce Humility, Not Pride
True assurance does not make a person proud.
It makes him grateful.
If you know you are saved, you should not look down on others.
You should not become careless.
You should not treat sin lightly.
You should not boast in yourself.
You should say:
“Thank God for mercy.”
“Thank God for Jesus Christ.”
“Thank God for His Word.”
“Thank God for grace.”
“Thank God He saved me.”
1 Corinthians 1:31 says:
“That, according as it is written, He that glorieth, let him glory in the Lord.”
— 1 Corinthians 1:31, KJV
The saved person has nothing to boast in but the Lord.
Assurance should lead to worship.
It should lead to obedience.
It should lead to love.
It should lead to courage.
It should lead to holy living.
It should never lead to spiritual laziness.
Assurance Should Not Make You Careless
Some people wrongly think assurance means:
“Since I am saved, I can live however I want.”
That is not biblical assurance.
That is deception.
Romans 6:15 says:
“What then? shall we sin, because we are not under the law, but under grace?
God forbid.”
— Romans 6:15, KJV
Grace is not permission to sin.
Assurance is not permission to drift.
The true believer says:
“Because Christ saved me, I want to please Him.”
“Because God had mercy on me, I do not want to return to darkness.”
“Because I belong to Jesus, I want to walk worthy of Him.”
Assurance should strengthen discipleship, not weaken it.
A person who uses assurance to defend sin has misunderstood both assurance and salvation.
Assurance Helps You Serve God With Confidence
Without assurance, a sincere believer may become spiritually paralyzed.
He may be constantly asking:
“Am I saved?”
“Did God really forgive me?”
“Can I pray?”
“Can I serve?”
“Does God receive me?”
“Am I still condemned?”
But when assurance is rightly grounded in Christ, the believer can move forward.
2 Timothy 1:12 says:
“…for I know whom I have believed,
and am persuaded that he is able to keep that which I have committed unto him against that day.”
— 2 Timothy 1:12, KJV
Paul did not say, “I know how strong I am.”
He said:
I know whom I have believed.
That is assurance.
Not confidence in self.
Confidence in Christ.
The believer who knows whom he has believed can serve, grow, pray, witness, worship, and endure with holy confidence.
Examine Yourself Without Despair
The Bible does tell people to examine themselves.
2 Corinthians 13:5 says:
“Examine yourselves, whether ye be in the faith; prove your own selves…”
— 2 Corinthians 13:5, KJV
This is important.
No one should be careless with his soul.
Do not assume you are saved merely because of family, church background, baptism, religious words, or a past memory.
Examine yourself honestly.
But examination should not become endless self-torture for someone who is truly looking to Christ.
The purpose is not to make sincere believers despair.
The purpose is to expose false confidence and lead the soul to truth.
Ask:
Am I trusting Jesus Christ?
Have I turned from defending sin?
Do I desire to follow Him?
Do I receive His Word?
Do I grieve over sin?
Do I see evidence of His work in me?
Is my hope in Christ alone?
If the answer reveals that you have been trusting the wrong thing, come to Christ now.
If the answer shows that your hope truly is in Christ, then rest in Him and continue following.
When You Lack Assurance, Go to Christ
If you lack assurance, do not merely stare at yourself.
Go to Christ.
Matthew 11:28 says:
“Come unto me, all ye that labour and are heavy laden,
and I will give you rest.”
— Matthew 11:28, KJV
Jesus does not call heavy souls to run away.
He says, “Come unto me.”
If you are afraid, come.
If you are confused, come.
If you are convicted, come.
If you are weary, come.
If you realize you have trusted the wrong thing, come.
If you are a sincere believer troubled by doubt, come.
Christ is not helped by your pretending.
Come honestly.
Say:
“Lord, I need You.”
“Lord, show me the truth.”
“Lord, I do not want false assurance.”
“Lord, I do not want needless fear.”
“Lord, help me trust You.”
The answer to doubt is not self-confidence.
The answer is Christ.
Simple Marks of Biblical Assurance
Here are simple questions to help you think biblically:
1. Is my faith in Jesus Christ?
Not in myself, my works, my religion, or my feelings.
2. Do I believe God’s promise?
God says those who believe on His Son have eternal life.
3. Has my heart turned from defending sin?
A saved person should not make peace with rebellion.
4. Do I desire to follow Jesus?
Not perfectly, but sincerely.
5. Do I receive correction from God’s Word?
A true disciple is teachable.
6. Do I see any fruit of new life?
Conviction, hunger for truth, love for God’s people, desire for obedience, grief over sin.
7. Where do I go when I fail?
A believer returns to God rather than making a home in sin.
These marks do not replace Christ.
They help you examine whether your faith in Christ is real.
What Assurance Sounds Like
Biblical assurance may sound like this:
“My hope is in Jesus Christ.”
“I know I have sinned, but Christ died for sins and rose again.”
“I am not trusting my goodness.”
“I am not trusting my religion.”
“I am trusting the Saviour.”
“God’s Word says the one who believes on the Son has everlasting life.”
“I still need to grow, but I desire to follow Jesus.”
“When I sin, I do not want to hide. I want to return to God.”
“My confidence is not in me. My confidence is in Christ.”
That is not pride.
That is faith resting in the promise of God.
Discipleship Questions
- Have you ever struggled with assurance of salvation? What caused the struggle?
- Why must assurance rest on God’s Word rather than feelings?
- What are some false foundations people use for assurance?
- How does a changed life support assurance without becoming the basis of salvation?
- Are you trusting Jesus Christ Himself, or are you trusting something else?
Closing Exhortation
You can know if you are saved.
Not because you are strong.
Not because you are sinless.
Not because your feelings never change.
Not because you have done enough good works.
Not because you had a religious experience.
You can know because God has spoken, Jesus Christ saves, and eternal life is promised to those who truly believe on the Son of God.
Do not rest in false assurance.
Do not comfort yourself with empty religion.
Do not claim Christ while making peace with sin.
But also, do not live in endless fear if your faith is truly in Jesus Christ.
Look to Him.
Believe His Word.
Examine yourself honestly.
Confess what needs to be confessed.
Reject false confidence.
Reject needless despair.
Trust the Saviour.
“These things have I written unto you that believe on the name of the Son of God;
that ye may know that ye have eternal life…”
— 1 John 5:13, KJV
A Prayer for Assurance
Lord, I do not want false assurance, and I do not want needless fear.
Search my heart.
Show me whether my faith is truly in Jesus Christ. Do not let me trust my works, religion, emotions, baptism, church background, or a past memory instead of Christ Himself.
If I have been deceived, open my eyes and bring me to true repentance and faith.
If I truly belong to You, help me rest in Your promises and stop living in fear.
Thank You that Jesus Christ is able to save. Thank You that Your Word is true. Thank You that eternal life is found in Your Son.
Help me walk in truth, humility, obedience, and confidence in Christ.
In Jesus’ name, amen.
Next Step
Take time today to read 1 John 5:11–13 slowly.
Then ask yourself:
“What does God say about eternal life?”
“Where is eternal life found?”
“Am I believing on the name of the Son of God?”
If your faith is in Christ, thank God for His promise and continue following Jesus.
If you realize your confidence has been in something else, come to Christ today.
