How do we know Christ is the Lord?

Romans 14:9 indicates that Christ died and rose again to be Lord of both the dead and the living. The New Testament consistently presents Jesus as the sovereign Lord, affirmed through His resurrection, which proves His authority over death and sin. As believers, we recognize His Lordship not merely through acknowledgment, but through our obedience and willingness to serve Him above all else. His role as the mediator and high priest also reinforces His position as Lord, underlining that His sovereignty encompasses every aspect of creation.
