raining spiritually

He’s the most difficult convert I have ever met. He doesn’t seem to have the least intellectual curiosity or natural piety. I asked him if Our Lord had more than one nature. He said, “Just as many as you say, Father” I said, “Suppose the Pope looked up and said it was going to rain would that be bound to happen?” “Oh yes, Father” “But supposing it didn’t rain?” “He said, “I suppose it would be sort of raining spiritually, only we were too sinful to see it."
