Is there a difference between something that is God's will and something that is within God's will?
Is there a greater good that includes the choice to do what's right or what's wrong?
Is there a need for evil to help define what's good - just as darkness and light work together to define what's visible?
Is God evil because He permits evil? Is He good because He permits choice?
Is it necessary ... is it even possible for us to comprehend the full extent of God's goodness; His providence; His wisdom?
Or do we just need enough of a taste of it to let us know what the banquet in heaven is all about?
