Charles Spurgeon said that doubt is a foot poised to go forwards or backwards in faith. We can never go forward without first picking up the foot. So stare into your doubts. But then look into the face of God, realize his power, and grasp the greatness of his love. And ask your questions. Leave room a God whose power and wisdom are far above your own and search the Scriptures to see what his answer might be. Humble doubts lead to deep faith.
