1 John 2:4-6

New Revised Standard Version, Anglicised Catholic Edition

⁴ Whoever says, ‘I have come to know him’, but does not obey his commandments, is a liar, and in such a person the truth does not exist; ⁵ but whoever obeys his word, truly in this person the love of God has reached perfection. By this we may be sure that we are in him: ⁶ whoever says, ‘I abide in him’, ought to walk just as he walked.
