The Lord said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool. The Lord shall send the rod of thy strength out of Zion: rule thou in the midst of thine enemies. Thy people shall be willing in the day of thy power, in the beauties of holiness from the womb of the morning: thou hast the dew of thy youth. The Lord hath sworn, and will not repent, Thou art a priest for ever after the order of Melchizedek. The Lord at thy right hand shall strike through kings in the day of his wrath. He shall judge among the heathen, he shall fill the places with the dead bodies; he shall wound the heads over many countries. He shall drink of the brook in the way: therefore shall he lift up the head. (Psalm 110)
Psalm 110 lets us in on a conversation between the LORD, the covenant God of the universe, and the Messiah at his right hand. It takes place in eternity, and at the throne of God almighty.
The LORD turns to the Messiah and swears an oath. God doesn’t need to swear at all. What He says always comes t pass…because He said it. He upholds all things by the Word of His power, His Word can never return void. “No Word of God is void of power”. The swearing of oaths is for our sakes, He want us to be assured in the strongest possible way.
Who does the LORD swear by? There is no one greater, so He swears by Himself as the inspired author of the Epistle to the Hebrews tells us,
For when God made promise to Abraham, because he could swear by no greater, he sware by himself, Saying, Surely blessing I will bless thee, and multiplying I will multiply thee. And so, after he had patiently endured, he obtained the promise. For men verily swear by the greater: and an oath for confirmation is to them an end of all strife. Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed it by an oath… (Hebrews 6:13-17)
The LORD would have all men everywhere to know that He has charged the Messiah, to be a Priest forever, after the order of Melchizedek.
Man, in his alienation from God, needs a mediator. He is unfit in every way to draw near to the Holy God. He has sinned and rendered himself unclean, defiled, and is at enmity against his Creator. He would perish in his corrupt state should He come nigh without the intercession of a qualified Priest.
The Messiah has been appointed to be Man’s Priest forever. This appointment was made long before the Priesthood of Levi was instituted in the Law of Moses, and remains all these years since the Levitical Priesthood has been discontinued.
What service does a Priest render? He is the bridge between God and Man, the one who keeps fellowship intact inspire of sin, weakness and failure which characterizes man and the absolute demands of Righteousness and Holiness which is essential for any kind of relationship with God.
The Priest satisfies all of the requirement of God, He stands between man and God as the representative man, He is Holy (We are not) , He has the “clean hands and the Pure Heart” God requires of humanity, thus He stands before God as our representative man.
A Priest also must make propitiation, (satisfaction). In all of the ways that we fall short of God’s perfection, someone has to answer to the offended righteousness of God, and to satisfy the demands of the broken Holy Law of God. The wages of Sin is death…. . Someone is going to have to pay the price of transgression, all accounts must be settled and the order of God’s universe must be restored.
God swore to the Messiah, even before the world began, that HE would be a Priest forever, that He would be the one who would make up the difference, the shortcomings, sins, transgressions and the demands of Holiness would be satisfied in Him, and that He would represent man before the infinitely Holy God, and He would bring the invisible God to man!
After all, He was and is uniquely qualified to do so, for He is at one and the same time, God and Man. The Messiah is the “seed of David” yet at the same time He is the “root of David”, thus David calls Him “Lord”. The LORD said unto my Lord, …You shall be A Priest forever, after the order of Melchizedek!
