1 My little children, these things write I vnto you, that ye sinne not. And if any man sinne, we haue an Aduocate with the Father, Iesus Christ the righteous:
2 And he is the propitiation for our sinnes: and not for ours onely, but also for the sinnes of the whole world.
3 And hereby wee doe knowe that we know him, if we keepe his commandements.
4 He that saith, I knowe him, and keepeth not his commandements, is a lyer, and the trueth is not in him.
5 But who so keepeth his word, in him verely is the loue of God perfected: hereby know we that we are in him.
6 He that sayeth he abideth in him, ought himselfe also so to walke, euen as he walked.
1 Jn 2:1-6
