Sowing and Reaping is a vintage religious studies text by Dwight Moody that talks about Christian life and worship. This Christian classic contains this passage: "We might as well try to blot the sun out of the heavens as to blot this truth out of the Word of God. It is heaven's eternal decree. The law has been enforced for six thousand years. Did not God make Adam reap even before he left Eden? Had not Cain to reap outside of Eden? A king on the throne, like David, or a priest behind the altar, like Eli; priest and prophet, preacher and hearer, every man must reap what he sows. I believed it ten years ago, but I believe it a hundred times more to-day."
