1 John 2:3-6

3 This is how we know that we know him: if we keep his commandments.

4 He who says, "I know him," and doesn't keep his commandments, is a liar, and the truth is not in him.

5 But whoever keeps his word, God's love has most assuredly been perfected in him. This is how we know that we are in him:

6 he who says he remains in him ought himself also to walk just like he walked.
