If you had the knowledge and power to stop the terrorist attack in London, would you have done so? Of course. In fact, if you could have stopped it but didn’t, we would call you morally deficient. We would partially blame you for the attacks!
What does this say about the supposedly all-loving, all-knowing, all-powerful God? He didn’t stop it. Some would say it’s because He doesn’t exist.
When the attack hit, I was in London to speak at several churches about my book titled I Don’t Have Enough Faith to be an Atheist. The morning after the attack I decided to change my topic to “If God Exists, Why is there Evil in the World?”
While I can’t present a complete answer to that question in this short column, the one thing the attacks fail to prove is that there is no God. In fact, if the attack was truly a grave injustice—if it was truly evil—then it shows that God actually does exist.
Because 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. Evil is like a wound in your body: If you take the wound out of your body, you have a better body; if you take the body out of your wound, you have nothing. (That’s why we often describe evil as negations of good things. For example, we say the attack on London was immoral, unjust, inhumane, not right, etc.) In other words, there would be no such thing as evil unless good existed, but there would be no such thing as good unless God existed.
C.S. Lewis was once an atheist who thought all the injustice in the world disproved God. He later realized he was stealing a moral standard from God in order to argue against Him. He wrote in Mere Christianity, “[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?”
As an atheist, Lewis was comparing this unjust universe to God’s perfectly just nature while claiming that God didn’t exist. In effect, Lewis was sitting in God’s lap to slap his face.
While the Nazis were bombing London in WWII, the Christian Lewis was on the BBC saying things such as:
The moment you say that one set of moral ideas can be better than another, you are, in fact, measuring them both by a standard, saying that one of them conforms to that standard more nearly than the other. But the standard that measures two things is something different from either. You are, in fact, comparing them both with some Real Morality, admitting that there is such a thing as a real Right, independent of what people think, and that some people's ideas get nearer to that real Right than others. Or put it this way. If your moral ideas can be truer, and those of the Nazis less true, there must be something—some Real Morality—for them to be true about.
Likewise, to rightfully condemn the London attacks, there must be an unchanging standard of goodness, righteousness, and justice that is beyond the terrorists and us. That standard is, by definition, the essence of the greatest possible Being, which is what we call “God.”
Without God there is no objective, authoritative, moral standard beyond humanity, which means human beings have no moral obligations and every action or behavior is merely a matter of human opinion. Do you think the London terrorist attack was wrong? Without God, that’s just your opinion against that of ISIS. The murder of six million Jews? It’s just your opinion against Hitler’s opinion. The sexual abuse of children? It’s only wrong if God exists.
If evil is real—as headlines from London 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.
But which God? The terrorists would claim that they were following the commands of Allah, particularly Suras 8 and 9 in the Qur’an. Ironically, Allah isn’t a viable candidate for the standard of Good because, according to Islamic doctrine, Allah is arbitrary. Whatever Allah does is good. By contrast, the God of the Bible is revealed as the unchanging ground of all Goodness. He isn’t arbitrary—He is Goodness.
If the God of the Bible actually exists, why would He allow evil to occur? There are several revealed and philosophical answers to that question that I cited in my presentation that Sunday at Kensington Temple in London (and more completely in my book Stealing from God: Why atheists need God to make their case.).
Regardless of the reasons, evil is a problem for every worldview including atheism. But Christianity is the only worldview equipped to handle it. In fact, the entire Christian story is an answer to the problem of evil. God Himself provides the ultimate solution—He takes evil on Himself. Jesus attaches humanity to His Divine Nature and allows the creatures who introduced evil into the world to torture and kill Him so we could be reconciled to Him. He takes the punishment for our evil deeds and offers forgiveness as a gift.
Christ’s gift isn’t the subject of a fictional story—there’s very good evidence that the story is actually true. That means you have the real opportunity to accept that gift right now. When Jesus comes back to finally quarantine evil in a place called hell, the time for choosing will be over. The Being whose essence is justice has to accomplish final justice at some point.
