Idolatry is much more interesting than atheism.

“So much modern theology continues to presuppose the deistic assumption that the first step in theology is to convince modern people that God exists… . Christian theology should be preoccupied with the more biblical question, What kind of God exists? Even if contemporary theology could prove that God exists, such a god would probably not be the God we are called to worship—the God of Abraham, Isaac, Sarah, Mary, and Jesus. Idolatry is probably a much more interesting dilemma to biblical people than atheism.”
