The spread of Ruckmanism among independent Baptists churches contributed heavily to their downfall and lessened their soul-winning influence. Why did God allow this to happen?
Surprisingly, the results indicate that God did not merely "allow" this to happen. He did it deliberately. Independent fundamentalist Baptist churches continue to dominate the list of America's greatest mega-churches, but they are calling themselves "Community," "Bible," "Fellowship," "Neighborhood," and other names. Yet their statements of faith clearly show that they are independent fundamental Baptist churches.
So the question becomes "Why did God do this?" I can give three overlapping reasons. One is from the Bible, and two are only based on observation, but the simple answer is "Because it worked."
