He who says he abides in him, ought, himself, also, so to walk even as he walked.

And every one who has this hope in him purifies himself, even as He is pure.

(He who believes on the Son of God, has the testimony in himself. He who believes not God, has made him a liar, because he has not believed the testimony, which God has testified concerning his Son.)

We know that whoever has been begotten by God, does not sin; but he who is begotten by God, guards himself, and the wicked on does not lay hold on him.
