I recently read a series of lectures given by Carl Sagan, and one of the points he made was that it would have been absurdly simple for Abraham’s God to leave absolute, definitive proof of His existence. Proof that would convince the healthiest of skeptics (such as Sagan).
For instance, a passage in the Bible as simple as “The sun is a star,” or “An object in motion stays in motion,” or perhaps even Maxwell’s equations for electromagnetism. The scribes wouldn’t know what these things meant, couldn’t apply them, but this was God they were listening to. God could have made certain they recorded these things, reminded them repeatedly to write them precisely and keep copying it down through the ages. Fast forward several centuries, and you have pretty powerful evidence that a higher power was imparting wisdom to those ancient prophets, because those are things they simply could not have had knowledge of.
(In Sagan’s novel Contact, his idea was that a non-random pattern could be located several billion digits down in the constant pi. Calculate out 3.14159265…far enough, and you prove definitely that there is a higher power in the universe.)
The main argument Christians have against this point is that God is not obligated to leave us proof. Why should He? Perhaps He thinks faith is truly a virtue, or He wants us to discover the truth on our own, or He thinks that empirical evidence takes away from spiritual faith. This is the same objection Sagan heard from members of the audience during his lecture.
But it seems to me that God made quite a bit of effort to prove His existence, if the Bible is to be believed. In biblical times, He was everywhere from burning bushes to voices from the sky. He parted seas, turned women into salt, rained brimstone, flooded the earth, and even got in a one-upping game with the magicians of Egypt. Miracles were ubiquitous back then. And God didn’t just give them hints and arcane prophecies and clues – He was in their face. Sometimes He appeared to do this to scare nonbelievers and heathens into accepting His power, or to prove to people that He was their God and he could do anything (such as when He used a great deal of verse to convince Job).
In Exodus 4.1, when God instructed Moses to go to Egypt and free the children of Israel, Moses said, “…they will not believe me, nor hearken unto my voice: for they will say, The Lord hath not appeared to thee.” God agreed, and showed Moses that he could change a rod into a snake, his had leprous, and water into blood to convince the people. Skeptics today would love to see evidence like that. To prelude the miracles in Egypt, God said in Exodus 7.1, “And I will harden Pharaoh’s heart, and multiply my signs and my wonders in the land of Egypt.” Later, before parting the Red Sea and destroying the Egyptians, God said again, “And I will harden Pharaoh’s heart, that he shall follow after them; and I will be honored upon Pharaoh, and upon all his host; that the Egyptians may know that I am the Lord.”
Not only did God exhibit definitive proofs, by His own admission He provides such evidence for the explicit purpose of convincing skeptics and heathens. I’m not saying God is obligated to do anything. But plenty of religions, sacred texts, and mythologies claim the kinds of definitive miracles the god of the Bible exhibited. Even the heathen magicians of Egypt could manage turning rods into snakes. How are we supposed to know the difference? What sets the miraculous claims of the Bible apart from the miraculous claims of Hinduism, or the Aztec’s mythology, for example?
