1 John 2:1-6 Holman Christian Standard Bible (HCSB)
2 My little children, I am writing you these things so that you may not sin. But if anyone does sin, we have an advocate with the Father—Jesus Christ the Righteous One. 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.[a] This is how we know we are in Him: 6 The one who says he remains in Him should walk just as He walked.
