Sherry, first of all, as you said it yourself, it's your abuser's sin, NOT yours. You were a child that had no sayso in what happened to you. Moreover, you were probably scared into silence by your abuser and told that it was all your fault. At that age, you had nothing to base these lies on.
Because of what your abuser did to you, you learned things that no child should know or does know without the abuse. You were probably told or made to feel that the only way you would be loved or cared about or even accepted was by allowing the abuse. That's why you were promiscuous in your teen years. I know! I was there! You're looking for love and/or acceptance through sex... because that's what you were taught... wrongly, I might add!
Second and most important, it's NOT you that God sees as unclean. It's your abuser! God loves you and sees you as the innocent child you were at three. He accepts you just as you are. When you accept
God's unconditional love for you, then will be the time when you will be able to accept yourself just as you are,
no shame, no guilt.
I accept you just as you are and I don't see you as unclean, shameful or guilty of ANYTHING! ... not anymore than I see myself that way because of the abuse I went through. My abuser was female, too. It was quite a shock when my T put it into words "You were the victim of incestuous homosexual rape!"
It was THEIR uncleanliness, THEIR sin, NOT ours! You and I are INNOCENT of any of that.
