One of my favorite scenes in the movie Indiana Jones and the Last Crusade. In the scene, Indiana Jones must decide if he believes in his own worthiness to accomplish the quest. he has to ask himself if he believes that there is a way across. All the options are removed except one: take a step. So he does.
I know all the theology is not “right” in the scene. And while I don’t subscribe to the view that Biblical faith is a blind leap, the scene does help us understand everyone has to reach their own point of decision. No one can believe for you. We all have to believe for ourselves.
