1 John 2:3-6 HNV

3 This is how we know that we know him: if we keep his mitzvot.
4 He who says, "I know him," and doesn't keep his mitzvot, 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.
