I tried repenting a few years ago with some limited results and freedom. These were just my own words expressed to the Lord. I see now that nearly all of us haven't a clue what He meant by the word repent, as it is much more than words you speak. It works , no matter , what horror we went through. You have to mourn and self abhor God's way. See my Christmas surprise on my blog. Simple little rites to do , which seem very weird in our culture, but they get God's attention.
