Jesus began to speak in parables to the hard of heart, because though "seeing they do not see, and hearing they do not hear, nor do they understand" (Matthew 13:13). They are capable, but they are not willing, and so they do not try to understand and are blind and deaf to the words and ways of God.
Peter, on the other hand, was not capable. He could not walk on water, yet when Jesus said, "Come," Peter got out of the boat and walked on the water and came to Jesus (Matthew 14:29). Half way there he realized he couldn't do what he was doing, and sank, but for a brief time he did the impossible because he was willing to believe the impossible.
"O you of little faith, why did you doubt?" Jesus chastised Peter. God does not care what we can do, but what we will do.
Creator God, this world is marvelous, full of wonders. It displays Your wisdom and majesty. How great You are. You have power and authority over all things. And You are good. That's why You can promise that all things work together for good for those who love You and are called according to Your purpose.
God, may I keep my ears tuned to You, listening to Your words and following them. May I live a life full of joy and wonder. May I reflect Your wisdom and goodness in all that I do. May I walk in faith and see the greatness of my God.
