2. The Problem of Evil-Now that's the philosophical term, for the rest of us it means, "How can a loving God allow (insert suitably horrible circumstance) to happen?"
First things first, almost nothing bad that happens is the "wrath of God" unleashed on man. New Orleans didn't get destroyed because of the Deity Powers act or any such nonsense. If God acts, we'll all know it was Him.
Secondly, s*** happens. Guess what? Again using the New Orleans example, plenty of righteous and innocent people lost their lives because they were in that place at that time. The rain falls on the righteous and the unrighteous as the Good Book says!
Thirdly, keeping with our same example, we bring lots of things on our selves, call it karma or reaping what you sow but, New Orleans was destroyed by a hurricane and a storm surge that were abnormally powerful, why? The combination of the destruction of Louisiana coastal wetlands and climate change. Argue our part in that all you want, it is a fact we are contributors. Even then there would never have been a problem if it hadn't been for government corruption which caused a lack of maintenance on the levees. A few misplaced millions of dollars and viola! Instant disaster. Even then much loss of life could have been deterred if not for the stupidity of elected officials on every level of Government. Man hath wrought the destruction of New Orleans, not God.
Thirdly, Christian doctrine leaves no place for the Calvinistic fallacy of predeterminism. If God is just, we must have free will. If God is loving, we must have free will. If God desires us to love Him, we absolutely must have free will. Putting those last points together in a completely non-mystic format you get this:
People do stupid things. Most of the time that makes stupid things happen to us. Sefishness and idiocy (a working definition of sin) cause problems not just for us but for everyone around us and in the world, to the point that you cannot say that sin "a" caused result "b" in every case. I may get result "b" without doing "a," but rest assured I've done something equally stupid and caused someone else a result "b."
Finally, some things are impossible to understand. If God is all-loving and all-knowing, then there are some things I can't explain without His viewpoint, which I don't have so there ya go! Most stuff is explainable, though, with good theology and doctrine.
