In Exodus 17, Israel faces thirst in the wilderness and attack from the Amalekites, yet God faithfully provides water from the rock and victory over their enemies. In this message, we see how the rock points us to Jesus Christ—the Rock who was struck for sinners so that living water and the Holy Spirit might be given to His people. As we reflect on Pentecost Sunday, we are reminded that the Christian life is a wilderness journey, but God provides, sustains, and fights for His people until they safely reach the Promised Land.
