A child on the tenth story of a burning building cannot see the firefighters with their safety net on the street. They call up, “Jump! We’ll catch you. Trust us.” The child objects, “But I can’t see you.” The firefighter replies, “That’s all right. I can see you. We are like that child, evil is like the fire, our ignorance is like the smoke, God is like the firefighter, and Christ is like the safety net.
If there are situations like this where we must trust even fallible human beings with our lives, where we must trust what we hear, not what we see, then it is reasonable that we must trust the infallible, all-seeing God when we hear from his word but do not see from our reason or experience. We cannot know all God’s reasons, but we can know why we cannot know.
