2 My dear children,^(A) I write this to you so that you will not sin. But if anybody does sin, we have an advocate^(B) with the Father—Jesus Christ, the Righteous One. ² He is the atoning sacrifice for our sins,^(C) and not only for ours but also for the sins of the whole world.^(D)

⁹ If we confess our sins, he is faithful and just and will forgive us our sins^(A) and purify us from all unrighteousness.^(B)

³ All who have this hope in him purify themselves,^(A) just as he is pure.^(B)

⁸ The one who does what is sinful is of the devil,^(A) because the devil has been sinning from the beginning. The reason the Son of God^(B) appeared was to destroy the devil’s work.^(C)

¹³ Let us behave decently, as in the daytime, not in carousing and drunkenness,^(A) not in sexual immorality and debauchery, not in dissension and jealousy.^{(B) 14} Rather, clothe yourselves with the Lord Jesus Christ,^(C) and do not think about how to gratify the desires of the flesh.^[a](D)
