1 John 2:3-5

New Matthew Bible

³ And hereby are we sure that we know him: if we keep his commandments. ⁴ He who says, I know him, and does not keep his commandments, is a liar, and the truth is not in him. ⁵ Whoever keeps his word, in him is the love of God perfected in deed. And thereby we know that we are in him.
