Free will can be seen in the Bible from the very first pages (and onward), and in Genesis we can read about Adam naming the animals and eating the forbidden fruit together with Eve. God told Adam to not eat, and instead he did the contrary. The Bible is a book filled with examples of people who disobey God and even rebel against him, but there are christians today who amazingly deny that man has free will. Or they suggest that our will is bound by our nature, but since we can’t even get our nature against God’s will then we’re still stuck with the idea that man has no free will. Or can we freely choose which nature to have? NONE of the early church fathers taught against free will the first 300 years AD. Only the gnostics taught against it. If we have no free will, then the only outcome is that God is the author of sin.
