1 John 2:3-5 and in this we know that we have known him, if his commands we may keep;

YLT⁽ⁱ⁾ 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.
