2 He is the atonement for our sins, and not only for our sins but also for the whole world.
3 Now we know that we have come to know Him by this—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, in him the love of God is truly made perfect. We know that we are in Him by this—
6 whoever claims to abide in Him must walk just as He walked.
7 Loved ones, I am not writing a new commandment for you, but an old commandment—one you had from the beginning. This old commandment is the word you have heard.
8 Yet I am writing a new commandment for you, which is true in Him and in you, because the darkness is fading and the true light is already shining.
