This is a good question and I see where it is leading. I would contend that God created snakes. I would not contend that God created the Devil.

Some of these questions are beyond our earthly reasoning. I just abject that “God is the author of evil.” I agree that God uses evil to his glorification as the master of all.

The rest unknown I humbly lay at his feet until it is revealed to me.

He created the tempter and a choice with the tree. In essence, he created freedom to choose good or evil. But creating an opportunity doesn’t mean he created the evil.

And free will shouldn’t be capitalized. It’s just a gift that God gave humans to not love, and therefore to truly love. Without choice, there’s no love.

Again, you don’t have to throw out sovereignty and omnipotence to have free will if God created the freedom and designed a world where he directs our freedom to his ultimate good.

Strict Calvinism seems to imply God is only super duper powerful if he dictates everything a creature does. This fails to account for the fact that he may have the power and desire to create fully free creatures. This doesn’t make him less powerful, it makes him a person who wants relationship with non-robots.
