Greg Koukl was the first Christian teacher that showed me that it is possible to have an intellectual belief in God. He taught me not what to think, but how to think.
I am eternally grateful to this man, and pleased to know of his new book
“The Story of Reality: How the World Began, How It Ends, and Everything Important that Happens in Between”
Here is a speech he gave on the subject.

Excellent teaching!
