1. If God demands obedience from humans, then he should reveal Himself to humans.
2. God demands obedience from humans.
3. Therefore, God should reveal Himself to humans. (1,2 MP)
4. God does not, in fact, reveal Himself to humans.
5. If God does not, in fact, reveal Himself to humans, then this should frustrate human beings.
6. So, human beings should be frustrated by God not revealing Himself. (4,5 MT)
I don't think 5 follows. If God does not reveal himself to humans, it doesn't entail that human beings should feel frustrated. It's good that people have added that God has revealed himself in the Bible, but of course for God to reveal himself to all of humanity, He would have to do so continuously.
It seems that if everyone knew God existed, then faith in Him wouldn't be necessary. Yes,
we would have all the answers, possibly, to our theological questions and that would be less "frustrating". This would be comparable to the Garden of Eden, before the Fall.
1.) It is necessary to lack full knowledge of God to have faith.
2.) If God revealed Himself to all people, then faith wouldn't exist.
3.) God hasn't fully revealed Himself.
4.) Faith exists.
