I've listened to several of Carson's sermons in the past year. Although he is an A-level scholar, he has a gift for explaining complex concepts in the most understandable terms. He is gentle yet passionate, quietly provocative, Gospel-centered and deeply edifying in content. He reminds me of a Reformed Ravi Zacharias.
Carson also advocates theological paradox in the form of compatibilism.
In one sermon, I was delighted to hear him address the famous dilemma of the "immovable rock." You've heard it before:
Can an omnipotent God create a rock so heavy he is unable to move it? Say "no," and He must not be omnipotent. Say "yes," and it's the same result.
Carson wisely observed: this question doesn't point us to a limitation on the part of God; it points us to a limitation on the part of logic.
Brilliantly humble answer, that.
We might add: Since God IS omnipotent, He is not the least bit threatened by ridiculous questions!
We might further add that God can cause the rocks to cry out in praise, make them gush with fresh water and follow people around, and raise up sons for Abraham from them. Just look at what he's done with a handful of dirt.
