But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.

If we say that we have no sin, we deceive ourselves, and the truth is not in us.

If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.

If we say that we have not sinned, we make Him a liar, and His word is not in us.

The Test of Knowing Christ

My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous.

And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.

Their Spiritual State

I write to you, little children, Because your sins are forgiven you for His name’s sake.

Sin and the Child of God

Whoever commits sin also commits lawlessness, and sin is lawlessness.

And you know that He was manifested to take away our sins, and in Him there is no sin.

Whoever abides in Him does not sin. Whoever sins has neither seen Him nor known Him.

He who sins is of the devil, for the devil has sinned from the beginning. For this purpose the Son of God was manifested, that He might destroy the works of the devil.

Whoever has been born of God does not sin, for His seed remains in him; and he cannot sin, because he has been born of God.

In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.

If anyone sees his brother sinning a sin which does not lead to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death. I do not say that he should pray about that.

All unrighteousness is sin, and there is sin not leading to death.

Knowing the True—Rejecting the False

We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him.
