In reply to John J. Flanagan.

The difference between Calvin and Luther with predestination is holding fast to what the Scripture says and stopping to say something when the Scripture says nothing. The Bible (Romans 8:29 ESV) "For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers," talks about those being saved but does not state that others are predestined to hell. As you say, that would be a "logical" conclusion, but it is not stated in the Scripture. Consequently, Lutherans see the Biblical doctrine of predestination as a doctrine of the Gospel and not a doctrine pertaining to the Law. Calvin logically concluded where Luther stuck with what the Bible stated. Luther is on safer ground, Scripture alone, not scripture and reason.
