The sermon explores the familiar story of Jesus walking on water and Peter's attempt to join him, found in Matthew 14. It delves into the context of the disciples' exhaustion, the symbolism of the sea as chaos, and Peter's bold yet faltering faith. The message emphasizes how Jesus responds to our moments of doubt and fear, highlighting the compassion in his question, "You of little faith, why did you doubt?" This story has profound implications for our spiritual lives, especially when we face overwhelming circumstances that challenge our faith.
