Couple of things:
1) Saban is far from a saint. He has manipulated and lied to people with the best of them while maintaining a straight face. Please never confuse Saban with a great guy or a Godly man.
2) Divorce is no greater than any other sin that you and I commit daily. If we did not, we would have no need for a Risen Savior. As is, we need Him daily. A sin is a sin in the eyes of a Righteous and Holy God. Whether it is divorce, fornication, homosexuality, theft or even distain for others through words, there is no difference. All must come, repent and turn from their ways to the Savior that embraces them unconditionally if we do so.
