Few phrases are thrown around more casually—or more confidently—than the accusation that Christians believe in the “God of the gaps.” It is meant to suggest that belief in God is merely a placeholder for ignorance. The argument is that if people couldn’t explain a natural phenomenon, they imagined a supernatural being did it. Humanity always wants to find an explanation for the unexplained, but dubious explanations are destined to disappear as science advances. This critique misunderstands both the nature of God and the nature of explanation itself.
