How does Christ act as a gathering ensign for His people?

Christ acts as a gathering ensign for His people through the preaching of the Gospel. In Isaiah 11:12, we see God promising to set up an ensign for the nations, indicating that His people—those of every tribe and tongue—are called to gather around Him. This is not a work they accomplish on their own; it is God's sovereign grace that enables the elect to respond to His call. As the Gospel is proclaimed, believers are brought together under Christ, who draws each of His sheep to Himself, providing them with spiritual rest and unity in the body of Christ. This ensures that they remain connected to their source of strength and hope.
