Frequently viewed as evangelicalism’s foremost Christian apologist, William Lane Craig’s name is most often associated with his ministry organization Reasonable Faith, the name of his most famous book and also weekly podcast.
He's been around quite a while and for the longest time he was the "go-to" philosopher/theologian/apologist for Evangelical Christians when they were looking for rational answers about the Bible. He has seemed to have fallen out of favor of late, especially after he took he took a controversial (and arguably heretical) view of the nature of Christ.
He got pwned in his debate with Shelly Kagan, which was the only time I saw him completely out of his element and unable to respond with his usual tricks.
