Why is the concept of Christ as an ensign important for Christians?

In Isaiah 11:10, Christ is referred to as an ensign, serving as a banner that calls people to Him. An ensign in ancient times was used in battle to rally troops and signify unity. In Christian theology, this imagery is profound as it portrays Jesus as the central figure under which the nations can gather to receive salvation and truth. His role as the ensign is twofold; He not only signifies victory and triumph over sin but also invites believers into a community of faith where they find identity and value. This is especially important in understanding the Great Commission, where Jesus sends His disciples forth to share the gospel, embodying the truth and hope that He represents.
