For David himself says by the Holy Spirit, ‘The Lord said to my Lord, “Sit at My right hand until I put Your enemies as a footstool for Your feet.”’ (Ps. 110:1).
Christ quotes Psalm 110:1 and affirms that David spoke by the Holy Spirit. This shows the divine inspiration of Holy Scripture. David calls the Messiah “my Lord,” which means that the Messiah is not only David’s descendant, but the Lord who has divine authority higher than David. The words “Sit at My right hand” point to Christ’s exaltation, authority, and victory. Making His enemies a footstool for His feet shows that His kingdom will finally triumph over sin, death, and all opposing powers.
