I believe one of the most difficult things for Christians to do is to show grace.
I came across this article that paints a pretty good portrait. But be careful. It's rather emotional.
The Prodigal Daughter
What I said when a pastor friend asked me to preach after his daughter strayed.
By Patrick Nyaga
I often met with a minister friend to share everything from our family life, to personal struggles, to our ministry victories and challenges. One item that often came up was how to handle issues of discipline in the church. One day my friend shared with me how strict he was when dealing with matters of sexual immorality in the church.
"I preach righteousness," he said, "and I stand for it. If someone is caught in sin, I don't care who they are, they have to confess their sin before the whole church, and then I put them under discipline for six months. During this time they cannot do anything in the church except attend. This is necessary for the purity of the church, and I will never bend from that." I tried to offer a different, more nuanced, perspective, but he was convinced his way was the only way, so I let it be.
