As a fantasy writer, I know how frustrating it can be when someone you've made decides they want to go off and do something else other than what they're supposed to be doing. No, I'm not saying characters in books are real... that would be a completely different post. Just listen to what I'm trying to say, here =P
I can imagine God, up there watching us, thinking "No, don't do that! Go over there! That'll work better! What are you doing?!" Now of course, I don't know what God thinks, for sure. And of course He already knows what we're going to do. But do you know how much patience that must take? To watch us mess up time and time again, and yet He continues to forgive His children and show us what the right thing to do is. He never ceases to amaze me.
