We have much more to say about this in our blog post, "Morality and God".
1. EVIL IN THE WORLD ACTUALLY PROVES GOD EXISTS - If there's evil in the world, that means there's good in the world. If there's good, there must be a moral law, something that differentiates between good and evil.
If there's a moral law, there must be a moral law giver, someone who instituted that moral law, who is outside of OUR opinions or preferences. Thus God.
2. OBJECTIVE MORALITY POINTS TO GOD - Atheists (those who believe there is no God) have no grounds for saying ANYTHING is objectively right or wrong (objectively wrong means something is wrong regardless of where you come from or who you are (like rape, or torturing little children for fun)).
If there is ANYTHING that can be said is objectively (or truly) wrong (wrong outside of how each of us feels about it), this implies a God who set up a right and wrong (MORAL CODE) outside of our personal opinions.
AGAIN, this demonstrates that an atheist (according to their view point that no objective standard outside of our own opinions exists (that no God exists)), cannot say ANYTHING is objectively right or wrong in the world (according to their own worldview).
If there's anything OBJECTIVELY wrong in the world, that actually PROVES God exists.
THE FACT THAT THERE ARE THINGS IN THE WORLD (LIKE RAPE or torturing 3-year-olds for fun) THAT WE WOULD SAY WERE OBJECTIVELY WRONG MEANS THERE IS A GOD WHO EXISTS!
