I John 2:1-11 NKJV

1My little children, these things I write to you, so that you may not sin. And if anyone sins, #Rom. 8:34; 1 Tim. 2:5; Heb. 7:25; 9:24we have an Advocate with the Father, Jesus Christ the righteous. 2And #(Rom. 3:25); Heb. 2:17; 1 John 4:10He Himself is the propitiation for our sins, and not for ours only but #John 1:29also for the whole world. 3Now by this we know that we know Him, if we keep His commandments. 4He who says, “I know Him,” and does not keep His commandments, is a #Rom. 3:4liar, and the truth is not in him. 5But #John 14:21, 23whoever keeps His word, truly the love of God is perfected #(1 John 4:12)in him. By this we know that we are in Him. 6#John 15:4He who says he abides in Him #Matt. 11:29; John 13:15; 15:10; 1 Pet. 2:21ought himself also to walk just as He walked. 7Brethren, I write no new commandment to you, but an old commandment which you have had #John 13:34; 1 John 3:11, 23; 4:21; 2 John 5from the beginning. The old commandment is the word which you heard from the beginning. 8Again, #John 13:34; 15:12a new commandment I write to you, which thing is true in Him and in you, #Rom. 13:12; Eph. 5:8; 1 Thess. 5:4because the darkness is passing away, and #(John 1:9; 8:12; 12:35)the true light is already shining. 9#(1 Cor. 13:2); 1 John 3:14He who says he is in the light, and hates his brother, is in darkness until now. 10#(1 John 3:14)He who loves his brother abides in the light, and #2 Pet. 1:10there is no cause for stumbling in him. 11But he who #(1 John 2:9; 3:15; 4:20)hates his brother is in darkness and #John 12:35; 1 John 1:6walks in darkness, and does not know where he is going, because the darkness has blinded his eyes.
