How do we know Christ is our stronghold?

Christ is designated as our stronghold because He fulfills the covenantal promises made by God. Numerous scriptures, including 2 Corinthians 1:20, assert that all God's promises find their 'yes' in Him. He is the foundation upon which our faith stands, providing both shelter and strength amidst the troubles of life. The blood of the new covenant, instituted by Christ, signifies that He is the one who empowers our salvation and sustains us in hope. His continuing intercession and provision reassure us of our secure position before God, confirming that He alone is capable of meeting our spiritual needs.
