Why is Christ called our banner?

In the same way that a banner signifies presence and assurance during battle, Christ serves as our spiritual banner. He stands out as the embodiment of hope, sacrifice, and victory because through His crucifixion and resurrection, He accomplished what we could not—defeating sin and death. In Exodus 17, Moses' hands raised with the rod reflect the truth that God’s power and victory are made evident through Christ. As we look unto Jesus, our Captain, we are rallied together under His lordship, finding strength and encouragement to face life's struggles with unwavering faith.
