This sermon centers on Psalm 110 as a profound revelation of Christ's divine kingship, emphasizing His dual identity as both David's descendant and David's Lord, thereby affirming His deity and humanity. It highlights Christ's present reign at the Father's right hand, not as a future hope but as an ongoing, sovereign rule over all creation, subduing enemies through conversion and judgment. The psalm's call to rule in the midst of enemies underscores Christ's active, spiritual conquest of the world through the Church, His volunteer army of believers who serve willingly by grace. The sermon calls Christians to embrace their role as witnesses and soldiers, urgently sharing the gospel with those still in rebellion, confident that Christ's authority is unshaken and His kingdom advancing through faithful proclamation and prayer.
