1 John 5:17 says that every wrongdoing counts as sin, and that some sin does not lead to death. The apostle John is writing to Christian believers in the late first century, urging them to see sin clearly, to pray for one another, and to hold fast to the life they have in Christ. The verse sits within a short passage about prayer and assurance.
All unrighteousness is sin, and there is a sin not leading to death.

What 1 John 5:17 Means
John begins with a broad statement: “all unrighteousness is sin.” Unrighteousness here means anything that falls short of what is right before God, whether a failure of love, an act of dishonesty, or a turning away from God’s ways. John refuses to shrink sin down to a few obvious wrongs. Every deviation from God’s righteous standard belongs in that category.
Then he adds that “there is a sin not leading to death.” The word “death” in this letter points to a settled separation from God and from eternal life, which is the outcome John contrasts with the life believers already possess. He does not spell out in this verse what that other kind of sin looks like, and he does not make it a rule that every sin must end in death. The verse leaves room for sin that can be prayed over and forgiven within the community of faith.
What the verse does not do is give a list of safe sins or a formula that guarantees forgiveness for any given act. It also does not tell believers to stop praying for everyone who falls, since verse 16 explicitly encourages asking God for life for a brother who sins without leading to death.
The Context of 1 John 5:17
First John was written to a community that had been troubled by teachers who denied that Jesus came in the flesh and who claimed to be free from sin. John answers them by insisting that the truth shows up in how people live. Obedience, love for fellow believers, and honesty about sin are the marks of genuine life in Christ. Verses 14 and 15 open the section by affirming that God listens when we ask according to his will, and verse 16 applies that confidence to praying for a fellow believer who has fallen.
Read this way, verse 17 is not a theological puzzle cut off from its neighbors. It is the middle of a pastoral instruction. Right after it, verses 18 through 20 assure believers that those born of God keep themselves and that the Son has given them understanding of the true God. The verse therefore calls the community to take sin seriously while trusting the God who protects and gives life.

A Short Prayer From 1 John 5:17
Father, you see every wrong I have done, whether I have noticed it or not. Thank you that you do not treat my failures lightly, and also that you are willing to forgive and give life. Show me where I have fallen short of your righteousness this week, and give me the courage to confess it honestly to you. Help me to pray for those around me who are struggling, trusting that you hear me and that you give life. Keep me close to you and to my brothers and sisters in Christ. Amen.
