How do we know that Christ is our banner?

Christ is our banner as evidenced by His role in fulfilling the law and achieving victory over our adversaries. In Exodus, Moses' raised hands, symbolizing God's authority, pointed to Christ who is our ultimate High Priest and sacrifice. Hebrews 2:10 emphasizes that Christ is the captain of our salvation, perfecting our faith through His sufferings. When Jesus was lifted up on the cross, He became the visible manifestation of God's victory over sin and death, serving as the banner under which we rally as believers. This assurance enables us to overcome our internal and external battles, as we continually look to Him, the author and finisher of our faith.
