What does the Bible say about the rod of God?

In Exodus 4, the rod that Moses carries represents both God's power and the gospel of Christ. When Moses is instructed to cast his rod on the ground, it transforms into a serpent, illustrating how God's authority can overcome sin and the devil. This rod, which Moses holds, is not merely a shepherd's staff; it symbolizes the means by which God delivers His people and provides guidance through the gospel. The rod of God typifies Christ, who leads His sheep through the preaching of the gospel, sanctifying His elect and establishing them in faith.
