Believe in something larger than yourself. . . get involved in the big ideas of your time.
If there is a Creator-God, it has used methods of creation that are indistinguishable from nature, it has declined to make itself known for all of recorded history, it doesn't intervene in affairs on earth, and has made itself impossible to observe. Even if you believe in that God. . . why would you think it would want to be worshiped?
