As Islamists continue to kill innocents, they provide more fuel for the oft-made atheist claim that religion is evil. Atheist Richard Dawkins condemned the recent attacks in France by tweeting, "No, all religions are NOT equally violent. Some have never been violent; some gave it up centuries ago. One religion conspicuously didn't."
Dawkins is right that some religions and religious people have consistently perpetrated evil. Atheists often use this fact to support atheism. However, the existence of evil turns out to be a bigger problem for atheists to explain than for theists. The kind of evil Dawkins and the rest of the civilized world abhor doesn't disprove God—it disproves atheism.
While it's commonly thought that only theists have to explain the existence of evil, the truth is every worldview does. Eastern pantheistic religions try to get around the problem by denying that evil even exists. Evil is an illusion, they say (and according to them, so are you!). Theists say evil is real and try to explain how evil and God can coexist. Atheists tend to be caught in the middle. In one breath they are claiming there is no good, evil, or justice because only material things exist—we are just material molecular machines "dancing to the music" of our DNA (as Dawkins himself put it). In the next breath they are outraged at the great injustices and evil done by religious people in the name of God.
Well, atheists can't have it both ways. Either evil exists or it doesn't. If it doesn't exist, then atheists should stop complaining about the "evil" religious people have done because they haven't really done any. They've just been "dancing to the music" of their DNA. If atheism is true, all behaviors are merely a matter of preference anyway. On the other hand, if evil actually does exist, then atheists have an even bigger problem. The existence of evil actually establishes the existence of God.
To explain why, we need to go back to Augustine who puzzled over the following argument:
God created all things.
Evil is a thing.
Therefore, God created evil.
How could a good God create evil? If those first two premises are true, He did, and this is a God problem. So, God must not be good after all. But then Augustine realized that the second premise is not true. While evil is real, it's not a "thing." Evil doesn't exist on its own. It only exists as a lack or a deficiency in a good thing.
Evil is like rust in a car: If you take all of the rust out of a car, you have a better car; if you take the car out of the rust, you have nothing. Or you could say that evil is like a cut in your finger: If you take the cut out of your finger, you have a better finger; if you take the finger out of your cut, you have nothing. In other words, evil only makes sense against the backdrop of good. That's why we often describe evil as negations of good things. We say someone is immoral, unjust, unfair, dishonest, etc.
We could put it this way: The shadows prove the sunshine. There can be sunshine without shadows, but there can't be shadows without sunshine. In other words, there can be good without evil, but there can't be evil without good.
So evil can't exist unless good exists. But good can't exist unless God exists. In other words, there can be no objective evil unless there is objective good, and there can be no objective good unless God exists. If evil is real—as the recent headlines from France plainly reveal—then God exists. The best evil can do is show there's a devil out there, but it can't disprove God. The very existence of evil boomerangs back to show that God exists.
C. S. Lewis was once an atheist who thought evil disproved God. He later realized he was stealing from God in order to argue against Him. He wrote, "[As an atheist] my argument against God was that the universe seemed so cruel and unjust. But how had I got this idea of just and unjust? A man does not call a line crooked unless he has some idea of a straight line. What was I comparing this universe with when I called it unjust?"
Stealing from God is what atheists tend to do when they complain about evil done in God's name. Richard Dawkins is correct that religious people have done evil things, but his atheism affords him no objective standard by which to judge anything as good or evil. So he steals goodness from God while claiming He doesn't exist. Dawkins has to sit in God's lap to slap His face.
Just who is this God? Allah isn't a candidate because according to Islamic doctrine Allah is arbitrary, and thus can't be the unchanging standard of good. The true God is the God of the Bible who is revealed as the unchanging ground of all goodness.Source: http://goo.gl/RaAm6v
