Chuck Smith emphasizes the importance of being directed by God in our service to Him, highlighting that the desire to serve is inherent in every believer. He warns against non-directed service, where individuals rely on their own ideas rather than God's guidance, and stresses that love should be the primary motivation for serving. Through the story of Peter's obedience to Jesus' command to 'launch out,' Smith illustrates that true success in service comes from following God's direction, even when it contradicts our own understanding. The sermon concludes with the transformative effect of this obedience on Peter, leading him to humility and a commitment to follow Jesus wholeheartedly.
