Consider David.
When you really think about it, he was Michael Corleone in a shepherd suit. Everything in his personal life, family life, and public life wasn't worth spit. He was a great warrior 'til he hit mid-life crisis time, but even that wasn't him.
Like he says, "Blessed is the man whose sins are forgiven..."
I'll let everyone else attempt this saintliness gig on their own.
I am definitely a Christian life Calvinist. Calvin nails Romans 7. Wesley and Arminius blew it.
