is that the food they eat does them good, or why man cannot live long without food. But if a man were to decline to eat until he knew all about the use of food, you would consider him mad. The benefit of the food does not at all depend upon ability to understand its effects. So with the knowledge of the truth.

155. M. But what is the good of believing in the doctrine of the Trinity¹?

C. It enables us to believe in the truth of Christ's claims to be the Word of God or the Son of God, and to accept the salvation which He offers. If the doctrine of the Trinity is not true, then Christ was not what He professed to be. He was not even a true prophet if His teaching was untrue. Thus disbelief in the doctrine of the Trinity overthrows both Christianity and Islam. Again

Muslims often ask such questions as this: "If Christ was God, who ruled the world when Christ was in the grave?" No one who believed the doctrine of the Trinity would ask such a silly question.

156. M. We want logical¹ proof, and what you say falls short of that.

C. Different² subjects require different kinds of proof. Were I to demand from you chemical proof of Alexander the Great's existence, or historical proof of the composition of water, or mathematical proof of the resurrection of the dead, you would justly declare the demand absurd. What kind of proof convinces you of the truth of the doctrine of the resurrection of the dead, of life after death, of rewards and punishments in the next world?
