2My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous; 2and he is the atoning sacrifice for our sins, and not for ours only but also for the sins of the whole world.
3 Now by this we may be sure that we know him, if we obey his commandments. 4Whoever says, ‘I have come to know him’, but does not obey his commandments, is a liar, and in such a person the truth does not exist; 5but whoever obeys his word, truly in this person the love of God has reached perfection. By this we may be sure that we are in him: 6whoever says, ‘I abide in him’, ought to walk just as he walked.
