All Christians are black sinners before they get converted, and most do not get cleaned up right away.
The blackest sinner is the one who denies any sin.
God can use black sinners like us to get His message out. Do you think Newton is the only corrupt Christian that ever was?
The GOOD NEWS is that we can be saved, and imperfect people can help.
"Amazing Grace" is an important part of Christianity as well as folk music, so it will survive--forever.
