'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 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.

My children, these things I write to you in order that ye may not sin; and if any one sin, we have a patron with the Father, Jesus Christ the righteous;

Every one that practises sin practises also lawlessness; and sin is lawlessness.

And ye know that he has been manifested that he might take away our sins; and in him sin is not.

Whoever abides in him, does not sin: whoever sins, has not seen him or known him.

He that practises sin is of the devil; for from the beginning the devil sins. To this end the Son of God has been manifested, that he might undo the works of the devil.

Whoever has been begotten of God does not practise sin, because his seed abides in him, and he cannot sin, because he has been begotten of God.

If any one see his brother sinning a sin not unto death, he shall ask, and he shall give him life, for those that do not sin unto death. There is a sin to death: I do not say of that that he should make a request.

Every unrighteousness is sin; and there is a sin not to death.

We know that every one begotten of God does not sin, but he that has been begotten of God keeps himself, and the wicked one does not touch him.
