Short answer: Yes. The Bible promises that God forgives every sin that is confessed and repented of, through the death of Jesus Christ. The only sin Jesus says will not be forgiven is blasphemy against the Holy Spirit, which is a hardened, final refusal of his mercy, not something a repentant person can fall into. If you are asking out of sorrow for what you have done, the answer for you is yes.

This is one of the questions I hear most from people who already believe, not from skeptics. Someone has done something they can barely say aloud, or they have fallen into the same sin again and again, and the doubt begins: surely this is the one that is too much.
I want to lay out the promise first, deal honestly with the exception, then look at two hard cases: the very worst sins, and the sin you cannot seem to stop repeating. The article is long because the question matters.
What Does 1 John 1:9 Promise?
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.1 John 1:9 (NIV)
Look at the words carefully, because they are doing precise work. "If we confess": the condition is honest agreement with God that what we did was wrong. The word for confess literally means to say the same thing, to agree. "He is faithful and just": the ground of forgiveness is not our performance or our feelings but God's own character. He promised, and he keeps promises. And "just": God can forgive without ceasing to be righteous, because the penalty was paid on the cross. The Judge himself took the sentence.
"Forgive us our sins" is paired with "purify us from all unrighteousness." Forgiveness clears the record. Cleansing begins to change the person. The verse says "all," and does not say "most."
The same promise runs through Scripture, from the Old Testament to the New. Psalm 103 says "as far as the east is from the west, so far has he removed our transgressions from us" (Psalm 103:12). Hebrews says that where sins have been forgiven, "an offering for sin is no longer necessary" (Hebrews 10:18). And Paul puts it this way: "Therefore, there is now no condemnation for those who are in Christ Jesus" (Romans 8:1).
There is a lot of material here, and my longer article on what the Bible says about forgiveness of sin covers it in greater depth.
Is There One Exception?
Yes, and I would be dishonest to skip it. Jesus said:
And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven.Matthew 12:31 (NIV)
This is the unforgivable sin. In its context, the religious leaders watched Jesus do plainly good things by the Spirit's power and called it demonic. It is not a single word or thought but a hardened, final stand against the very one who offers forgiveness. If a person will not receive pardon from the Spirit, there is no other source to which they can go.
The key point is this: a person who is troubled about whether he has committed it has not. The sin is characterized by indifference and hostility, not by anguish. I have written a fuller treatment in the unforgivable sin, and I encourage you to read it if this is what keeps you awake.
Some ask about "the sin that leads to death" in 1 John 5:16. Interpreters differ on what John means (spiritual death, apostasy, or physical judgment). Catholics connect it to what they call mortal sin. Nobody who reads it should conclude that Jesus will turn away a sorry sinner; John wrote the verse about forgiveness in chapter one of the same letter.
So the list of sins God will not forgive is: those which are never repented of. In that sense the people who sit outside forgiveness are those who will not come in, as the older preachers used to say.
Will God Forgive The Worst Sins?
The Bible gives us real examples, because it knows we will ask.
| Person | What They Did | What Happened |
|---|---|---|
| David | Adultery with Bathsheba and arranging her husband's death | Confessed; "The LORD has taken away your sin" (2 Samuel 12:13). Psalm 51 records his prayer. |
| Manasseh | Led Judah into idolatry and shed much innocent blood | Humbled himself and prayed; God heard and restored him (2 Chronicles 33:12-13). |
| Peter | Denied Jesus three times | Wept bitterly; restored by the risen Christ (John 21). |
| Saul (Paul) | Persecuted and imprisoned Christians, approved of Stephen's death | Met Christ; became an apostle. |
Paul himself drew the lesson. He called himself the worst of sinners, and then gave the reason God showed him mercy:
Christ Jesus came into the world to save sinners1 Timothy 1:15 (NIV)
He adds in the next verse that his case was meant as an example of Christ's "immense patience" for everyone who would believe. In other words, God picked the hardest case on purpose, so that no one would think theirs was beyond him.
Notice that none of these were minor. And forgiveness did not mean the consequences vanished. David's family suffered deeply afterward. Forgiveness restores our standing with God; it does not always remove what we have broken in the world. That is one reason repentance matters, and why it can include apology and restitution. If you want the practical outline, see how to repent.
What about the people who ask whether to confess to a priest or to God directly? Catholics teach that grave sins should be brought to a priest in the sacrament of Reconciliation. Protestants teach that we may confess directly to God and that Christ alone is our mediator. Both agree on the essential: God hears the broken heart. The Bible also teaches mutual confession among believers (James 5:16); see confessing your sins to one another.
What If I Keep Committing The Same Sin?
This is the form of the question that hurts most. You confessed it, you meant it, and last week you did it again. Has God finally had enough?
John anticipated exactly this. He writes, "My dear children, I write this to you so that you will not sin." That is the goal. Then comes the sentence that has comforted countless believers:
if anybody does sin, we have an advocate with the Father1 John 2:1 (NIV)
"Advocate" means someone who stands beside you in the courtroom. Jesus does not sit in the gallery waiting for you to fail; he speaks for you before the Father. Our standing does not rise and fall each time we stumble.
That is not permission. Paul asks, "Shall we go on sinning so that grace may increase?" and answers with a firm "By no means!" (Romans 6:1-2). The Christian life is meant to be one of growth, and a pattern that never troubles us is a warning sign. But the Bible's model for the sin that clings is not despair. It is repentance again, and again, and help from other believers, and the slow work of the Spirit. When Peter asked how often to forgive, Jesus said not seven times, but seventy-seven times. If he asks that of us, he does not give less.
Practical help is available on this site: how the Bible addresses habitual sin, how we overcome sins, and what the Bible says about sin after salvation. If shame is the loudest voice in your head, remember that conviction says "you did wrong, come back" while condemnation says "you are finished." Only the first comes from God.

Frequently Asked Questions
What sins will God not forgive?
Scripture names one: blasphemy against the Holy Spirit, the settled, final rejection of the Spirit's witness to Christ (Matthew 12:31). Anyone who is sorry for sin and wants to be forgiven has not committed it. See Mark 3:29 for the parallel warning.
Will God forgive the worst sins?
Yes. Scripture records forgiveness for murder, adultery, idolatry and the persecution of the church itself. Paul called himself the worst of sinners and said that was exactly why he received mercy (1 Timothy 1:15).
Can I confess my sins to God instead of a priest?
Yes, according to most Protestants, who point to 1 John 1:9 and to Christ as the one mediator. Catholics teach that grave sins should also be confessed to a priest in the sacrament of Reconciliation. Both traditions agree that God hears an honest confession.
What is the most committed sin?
The Bible does not rank sins by frequency, but pride, selfishness and failing to love our neighbour run through everything. Our article on pride is a good place to look at the root.
How many times will God forgive the same sin?
When Peter asked whether seven times was enough, Jesus said "seventy-seven times" (Matthew 18:21-22). That was about how often we should forgive, and it points to the character of the God who forgives us. He does not tire of the repentant.
