I am still ruminating over Psalm 110 this morning.
Jesus, the Highest King, owns all of creation and rules it completely according to the will of the Father.  It is His Kingdom and His rules apply.
Jesus is the Highest Priest, and has the highest spiritual authority granted by the Father.  He alone is the way to God, the intercessor, the sacrifice, and the redeemer.
Jesus is the Highest power judicially.  He is higher than any Supreme Court and His judgements are righteous and  final.

Paul wrote this in Ephesians 1:18-23  " I pray that the eyes of your heart may be enlightened so that you may know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints, and what is the surpassing greatness of His power toward us who believe. These are in accordance with he working of the strength of His might which He brought about in Christ when He raised Him from the dead, and seated Him at His right hand in the heavenly places, far above all rule and authority and power and dominion and every name that is named, not only in this age, but also the one to come.  And He put all things in subjection under His feet, and gave Him as head over all things to the church, which is His body, the fulness of Him who fills all in all." 

Paul also wrote in I Corinthians 15:24-28  that at the end,  He will deliver " up the kingdom to God and Father, when He has abolished all rule and power. For He must reign until He has put all His enemies under His feet. .. and when all things are subjected to Him, then the Son Himself also will be subjected to the One who subjected all things to Him, that God may be all in all." 

All that David wrote in Psalm 110 was accomplished in Jesus Christ as He lived, died, and rose from the grave.  The Father has established the rule of His only begotten Son... " for a child will be born to us, a son will be given us; and the government will rest on His shoulders; and His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace.  There will be no end to the increase of His government or of peace, on the throne of David and over His kingdom, to establish it and to uphold it with justice and righteousness from then on and forevermore. The zeal of the Lord of hosts will accomplish this." ( Isaiah 9:6-7)

Great are Your works, O Lord! How splendid and majestic is your work, Your gracious, compassionate, righteous work.. for You have "sent redemption to Your people"  You have made known Your power.  You have made known Your commandments and Your covenant.  You have given to us a great Savior, the Anointed One who is King, Priest, and Judge forever.  All praise to God, the Father, the Son, and the Holy Spirit. Amen.
