'Sin' in the Bible

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

If we say that we do not have sin, we deceive ourselves and the truth is not in us.

My little children, I am writing these [things] to you in order that you may not sin. And if anyone sins, we have an advocate with the Father, Jesus Christ the righteous [one],

Everyone who practices sin also practices lawlessness, and sin is lawlessness.

And you know that that one was revealed in order that he might take away sins, and in him [there] is no sin.

Everyone who resides in him does not sin. Everyone who sins has neither seen him nor known him.

The one who practices sin is of the devil, because the devil has been sinning from the beginning. For this [reason] the Son of God was revealed: in order to destroy the works of the devil.

Everyone who is fathered by God does not practice sin, because his seed resides in him, and [he is] not able to sin, because he has been fathered by God.

If anyone should see his brother sinning a sin not [leading] to death, he should ask, and he will grant life to him, to those who sin not [leading] to death. ([There] is a sin [leading] to death; I do not say that he should ask about that.

All unrighteousness is sin, and [there] is a sin not [leading] to death.)

We know that everyone who is fathered by God does not sin, but the one fathered by God, he protects him, and the evil one does not touch him.
