“We become too much like Peter when we relate to God based on getting what we want, which is really a way of saying that our faith is conditional.  Our trust is then not actually in the Lord, but in ourselves.  We may not ask to walk on the water, but we judge the importance of faithfulness to the Lord on whether He gives us the results that we want.  When things do not go as we would like, the weakness of our faith becomes clear, for then we sink into doubt, despair, and a lack of commitment to find the healing for our souls. “
