I would substitute forgiveness for acceptance. God forgives sin, He does not accept it. This is why , though Jesus refuses to cast the stone, He tells the woman to go and sin no more.
1 John 5-10
5 This is the message we have heard from him and declare to you: God is light in him there is no darkness at all. 6 If we claim to have fellowship with him and yet walk in the darkness we lie and do not live out the truth.7 But if we walk in the light,as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.
8 If we claim to be without sin we deceive ourselves and the truth is not in us 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
