How does an atheist measure evil?

Greg Bahnsen copy 2He wants to know about the problem of evil. My answer to the problem of evil is this: There is no problem of evil in an atheist’s universe because there is no evil in an atheist’s universe. Since there is no God, there is no absolute moral standard, and nothing is wrong. The torture of little children is not wrong in an atheist’s universe. It may be painful, but it is not wrong. It is morally wrong in a theistic universe, and therefore, there is a problem of evil of perhaps the psychological or emotional sort, but philosophically the answer to the problem of evil is you don’t have an absolute standard of good by which to measure evil in an atheist’s universe. You can only have that in a theistic universe, and therefore, the very posing of the problem presupposes my world view, rather than his own.Β

The Great Debate: Does God Exist?

Logical response

Greg Bahnsen copy 2Greg Bahnsen was debating a hostile atheist in a university in California. The man asked a question that was a great blunder.
“Is your God invisible and immaterial?”
“Yes, He is.”
“Can you tell me of anything else that is invisible and immaterial and real?”
“Yes,” replied Bahnsen, “the laws of logic.”
The audience broke out into an enthusiastic applause. The atheist was unable to recover from his mistake the rest of the debate.
