2 He Himself is the propitiation for our sins, and not only for ours, but also for those of the whole world.
3 This is how we are sure that we have come to know Him: by keeping His commands.
4 The one who says, “I have come to know Him,” yet doesn't keep His commands, is a liar, and the truth is not in him.
5 But whoever keeps His word, truly in him the love of God is perfected. This is how we know we are in Him:
6 The one who says he remains in Him should walk just as He walked.
7 Dear friends, I am not writing you a new command but an old command that you have had from the beginning. The old command is the message you have heard.
8 Yet I am writing you a new command, which is true in Him and in you, because the darkness is passing away and the true light is already shining.
