…we have to recognize that the problem of tragedy, injustice and suffering is a problem for everyone no matter what their beliefs are. Now, if you believe in God and for the first time experience or see horrendous evil, you rightly believe that that is a problem for your belief in God, and you’re right – and you say, ‘How could a good and powerful God allow something like this to happen?’
But it’s a mistake (though a very understandable mistake) to think that if you abandon your belief in God it somehow is going to make the problem easier to handle. Dr Martin Luther King, Jr., in his Letter from Birmingham Jail says that if there was no higher divine Law, there would be no way to tell if a particular human law was unjust or not. So think. If there is no God or higher divine Law and the material universe is all there is, then violence is perfectly natural—the strong eating the weak! And yet somehow, we still feel this isn’t the way things ought to be. Why not? Now I’m not going to get philosophical at a time like this. I’m just trying to make the point that the problem of injustice and suffering is a problem for belief in God but it is also a problem for disbelief in God—for any set of beliefs. So abandoning belief in God does not really help in the face of it.
