In his sermon, "Christians Eat Last," the pastor delivers a message centered on the theme of selflessness and service to others as the cornerstone of a fulfilling Christian life. He posits that true life is found not in self-preservation but in letting go of one's own needs and desires to serve God and other people. Using the Marine Corps motto "officers eat last" as an analogy, he encourages the congregation to adopt a similar mindset of prioritizing others. The sermon presents Jesus as the ultimate example of this self-sacrificial love, highlighting his life of service and ultimate sacrifice on the cross. It contends that when individuals live for others, they experience a more profound sense of peace and joy, as God fills the "empty cup" of a life poured out in service. The sermon concludes by emphasizing that the path to a great life is one of humility and service, even extending to those who have wronged us, as this is the key to a deeper and more meaningful experience of Jesus
