1 John 2:3 - 2:6
3 And by this we know that we have come to know Him, if we keep His commandments. 4 The one who says, “I have come to know Him,” and does not keep His commandments, is a liar, and the truth is not in him; 5 but whoever keeps His word, truly in him the love of God has been perfected. By this we know that we are in Him: 6 the one who says he abides in Him ought himself to walk in the same manner as He walked.
