1 John 1:9-10: Christ’s Finished Work

I John 1:9-10: If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say we have not sinned, we make him a liar, and his word is not in us. [1]

 John continues affirming sin and grace [2] in these final verses. Verse ten makes certain that you cannot deny sin and trust God and His Bible because denying sin throws away the Bible and its Divine author. [3] Simultaneously, the second half of verse nine portrays God’s forgiveness and cleansing as completed and not ongoing. [4] John’s language communicates that we need to grow, and makes definitive that the result of confessing our sins is a once and for all cleansing, forgiving, and purifying. [5]

 This is wonderful news for us because we continue warring with sin. [6] Nothing needs to be added to Christ’s finished work. Our sanctification does not earn salvation. [7] We strive to become more like Christ out of love for Him. [8] Today if you are in Christ you can face your challenges and grow in grace knowing that your standing before God never changes because He sees Christ’s light on you. [9] May that joy empower you.
