1 John 2:1-7

1 My little children, these things I write to you, that ye may not sin: and if any one may sin, an advocate we have with the Father, Jesus Christ, a righteous one,
2 and he -- he is a propitiation for our sins, and not for ours only, but also for the whole world,
3 and in this we know that we have known him, if his commands we may keep;
4 he who is saying, `I have known him,' and his command is not keeping, a liar he is, and in him the truth is not;
5 and whoever may keep his word, truly in him the love of God hath been perfected; in this we know that in him we are.
6 He who is saying in him he doth remain, ought according as he walked also himself so to walk.
7 Brethren, a new command I write not to you, but an old command, that ye had from the beginning -- the old command is the word that ye heard from the beginning;
