^3 (A)By this we know that we have come to ^(B)know Him, if we ^(C)keep His commandments. ⁴ The one who says, “^(D)I have come to ^(E)know Him,” and does not keep His commandments, is a ^(F)liar, and ^(G)the truth is not in him; ⁵ but whoever ^(H)follows His word, in him the ^(I)love of God has truly been perfected. ^(J)By this we know that we are in Him: ⁶ the one who says that he ^(K)remains in Him ^(L)ought, himself also, to walk just as He walked.

^7 (M)Beloved, I am ^(N)not writing a new commandment to you, but an old commandment which you have had ^(O)from the beginning; the old commandment is the word which you have heard. ^8 [a]On the other hand, I am writing ^(P)a new commandment to you, which is true in Him and in you, because ^(Q)the darkness is passing away and ^(R)the true Light is already shining. ⁹ The one who says that he is in the Light and yet ^(S)hates his ^(T)brother or sister is in the darkness until now. ^10 (U)The one who loves his brother and sister remains in the Light, and there is nothing in him to cause stumbling. ¹¹ But the one who ^(V)hates his brother or sister is in the darkness and ^(W)walks in the darkness, and does not know where he is going because the darkness has ^(X)blinded his eyes.
