Yoḥanan Aleph (1 John) 2:3-6

And by this we know that we know Him, if we guard His commands. The one who says, “I know Him,” and does not guard His commands, is a liar, and the truth is not in him. But whoever guards His Word, truly the love of Elohim has been perfected in him. By this we know that we are in Him. The one who says he stays in Him ought himself also to walk, even as He walked.
