In this verse-by-verse study of Mark 9:38-41, we examine a fascinating moment where the disciples move from arguing about their own greatness to trying to police the ministry of others. Titled “Water Works,” this teaching explores the tension between the “all-out intensity” of spiritual warfare and the “steady aim” of simple, everyday Christian service.

The passage begins with the Apostle John reporting that the Twelve tried to stop a man from casting out demons because he was not part of their specific group. From a Calvary Chapel perspective, we see here the recurring struggle of the flesh: the desire for exclusive “tribalism” and the pride that often creeps into ministry. It is deeply ironic that the disciples tried to forbid a successful exorcism shortly after they themselves had failed to cast out a demon earlier in the chapter.

Jesus provides a gentle but firm correction that remains vital for the church today. He teaches that “whoever is not against us is for us,” reminding us that while we may not partner with every group or denomination in every endeavor, we can certainly be allies in the Gospel. We explore the distinction between being a “partner” and an “ally,” and how we can maintain a firm commitment to biblical truth while extending the right hand of fellowship to genuine brothers and sisters in Christ.

The study then pivots to the “Water Works” mentioned in verse 41. Jesus elevates the simplest act of hospitality—giving a cup of cold water in His name—to the same level of eternal reward as performing a miracle. This is a beautiful revelation of God’s grace and His desire to reward His children. In the Kingdom of God, the “gold medal” isn’t reserved only for those with a platform or a title; it is promised to the servant who is observant enough to see a brother or sister in need and humble enough to meet it.

If you are searching for a deeper understanding of the Gospel of Mark or looking for a Calvary Chapel Bible study that focuses on practical Christian living and servant leadership, this video is for you. Join us as we learn to look past our own prestige and instead look for those who are “thirsty,” learning to serve in the name of Jesus for His glory alone.
