Why Doesn’t God Show Himself?

Is it reasonable for us to think we can fully understand why God does certain things and not others? Why or why not?

Although the Bible does not directly address the question, “Why doesn’t God show himself to everyone and prove that he exists?,” are there logical reasons why he doesn’t show himself to every single person on earth? If so, what are some of those reasons?

Why would coming to believe in God be useless if a person is unwilling to submit to God’s authority over his or her life?

Though God chooses not to show himself to everyone directly, are we still capable of rationally comprehending his existence and will for us? What kinds of evidence has he left to confirm his existence and will us for?
