ESVEnglish Standard Version
3And by this we know that we have come to know him, if we keep his commandments. 4Whoever says "I know him" but does not keep his commandments is a liar, and the truth is not in him, 5but whoever keeps his word, in him truly the love of God is perfected. By this we may know that we are in him: 6whoever says he abides in him ought to walk in the same way in which he walked.
