In the realm of theology, the philosopher and the believer ask basically the same question, but from two very different angles, which are like a circle and its center.
The philosopher says, “The world exists, so how can there be a God?”
He is trying to find a way from the circumference to the center.
The believer, on the other hand, says, “God exists; how, then, can there be a world?”
He tries to find a path connecting the center to the circumference.
Sometimes, both the philosopher and the believer are successful; they find good answers, and they meet.
When they fail, however, each of them is left with the question.
If one could choose, I think that rather than being left with the question “I am in the world; how can God exist?” it is far better to be left with “I am with God, I just do not understand how this world can exist.”
