I would like to get some help with Isaiah 45:7, which says, “I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.” (KJV) Is God the creator of evil? Can you recommend a good book on this?
God is not the creator of evil. Indeed, strictly speaking, evil is not a thing. It doesn’t exist in its own right, but only as a corruption or perversion of some good thing that God did create.
A better translation of this verse, given the context, is what you find at www.netbible.org:
I am the one who forms light and creates darkness;
the one who brings about peace and creates calamity.
I am the Lord, who accomplishes all these things.
God is sovereign and nothing happens apart from His will (Ephesians 1:11; etc.). This includes calamities and disasters of every kind. Although God is not always the efficient cause of such calamities, He nonetheless allows them to occur in accordance with His sovereign purposes for the world. Almost any good exegetical or expositional commentary on this verse will deal with the difficulty you’ve noticed.
