Roger Olsen makes some bold statements about Calvinism...
Many conservative Christians wince at the idea that God is limited. But what if God limits himself so that much of what happens in the world is due to human finitude and fallenness? What if God is in charge but not in control? What if God wishes that things could be otherwise and someday will make all things perfect?
That seems more like the God of the Bible than the all-determining deity of Calvinism. In this world, because of our ignorance and sinfulness, really bad things sometimes happen and people do really evil and wicked things. Not because God secretly plans and prods them, but because God has said to fallen, sinful people, "OK, not my will then, but thine be done -- for now."
And God says, "Pray because sometimes I can intervene to stop innocent suffering when people pray; that's one of my self-limitations. I don't want to do it all myself; I want your involvement and partnership in making this a better world."
It's a different picture of God than most conservative Christians grew up with, but it's the only one (so far as I can tell) that relieves God of responsibility for sin and evil and disaster and calamity.
The God of Calvinism scares me; I'm not sure how to distinguish him from the devil. If you've come under the influence of Calvinism, think about its ramifications for the character of God. God is great but also good. In light of all the evil and innocent suffering in the world, he must have limited himself.
