Where to start on this subject. There is so much about this.
I see a lot of this in counseling individuals that have come to Christ. The best thing to do is forgive the person that has offended you when you were a child. Sometimes this takes time, and not particularly easy to do. Sometimes the person just has to admit to God that they can't do it, and that He needs to help them forgive. He does. Nothing is impossible with God.
I've seen God take lives that are a hopeless mess, and turn them around into new creatures in Him. It can be done with God's help. Children who are raped and/or abused are "fragmented". They can take on characteristics of their offenders. There's so much that goes on, and gets passed back and forth in these acts. The person above that states she became a nymphomaniac is telling a not uncommon symptom after such episodes. God can heal that fragmentation in the emotions. Laying something tragic as this at Jesus feet, and leaving it there is not as easy as it sounds. We have a tendency to pick it right back up when we leave. Forgiveness is the key to release, and living a life in victory over that that hinders us.
Spanking a child to teach discipline does not cause negative emotions in an adult unless that adult is using it for an excuse for their own bad behavior. I've talked with various people that will "hold on" to a spanking or correction from their parents and call it abuse. It is not abuse. There is correction that is abuse, and can harm an adult in their later life and abuse their own children. Example: If the children saw daddy slap mommy and the kids around......they are likely to do the same when they get older. A pattern like that can be broken.
I tell people all the time....you had a bad childhood? Well, childhood is over, and now your an adult and can make your own choices and decisions. You are no longer bound by what happened in your childhood, because it's over. Someone who holds onto "slights" that happened to them as a child, is someone that wants to stay in that state and have people feel sorry for them......they need to grow up and enter adulthood. I've seen many people overcome horrible childhoods to become beautiful men and women of God who have such contributions to their church body and society as a whole.
Don't get me wrong, their are strongholds that have us bound from some things that happen to us in our childhoods (molestation is one), but God can remove those strongholds if we are willing to forgive and put them in his capable hands. That "frees" us to a new life. Again...Forgiveness is the key.
If you think I'm not talking from experience, you would be wrong. What I am today in Christ is nothing I was as a child. It's possible to rise above anything with God helping you. Real healing needs to take place, and only God can do that. Never hold onto hate and a desire for vengeance as it only destroys you. Believe me, God is the avenger, and will in no wise let anything go unpunished that is not repented of.
I could write reams on this subject, but only hit the highlights.
