Sin

"We all lose a part of our humanity, of our divinity when we sin -- when we betray our sacred relationship with one another or with God. When you sin, you feel awful. Because in many ways you end up knowing that it is not in your best interest, ultimately, and that often someone is going to be hurt by what you do. We often think of sin as a violation of religious or moral law or as an offense against God. But we sin whenever we are less than we could be, when we miss the mark of our potential to be fully lovingand caring human beings. These smaller sins also need forgivness, as of course do the larger violations of another's humanity and holiness."

-- Desmond Tutu, God Has a Dream

You don't know how many times I read and reread that.
