Hebrews 7

Jesus Christ, our Lord and Savior, our great and wonderful High Priest.
Jesus was not a descendant of Aaron. Jesus was not a son of the tribe of Levi, those who inherited the priesthood through Moses, who received word from God.
Jesus became a priest after the order of Melchizedek.
Melchizedek a priest of God.
And Melchizedek...he was the priest of the most high God.
Who ordained him a priest? God.
God ordained Jesus to be our High Priest.
Melchizedek was a priest not involved in the laws of Moses, he lived long before Moses lived, before the written laws were passed down, before the sacrificial ceremony enacted to teach every man of God that their sins have penalties and only through sacrifice to God could they escape the punish of sin- death everlasting.
Melchizedek and Jesus, both Priest not of the sacrificial system in place. Jesus became the ultimate sacrifice for us. Once the ultimate sacrifice was made no longer were animal sacrifices needed because the Great Redeemer, the Greatest Sacrifice of all was made. There could be no greater sacrifice, none. Once Jesus gave his life, making the typified the actual sacrifice needed to reconcile man with God, the actual and last sacrifice needed, animal sacrifices were hollow, no longer in effect, no longer had the power they once had.
The Great Sacrifice is also our Great High Priest. Reconciling God and man.
Is it no wonder we need to daily confess and repent of our sins, accepting the great sacrifice made for us by our Lord and Savior? He is our only hope, our only hope at reconcilation with our Heavenly Father. Sons and daughters that we are, the need to be reunited with our Heavenly Father is a desperate need. Reconcilation between a Father and His wayward children made possible through the sacrifice of His innocent Son.

Hebrews
{7:1} For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him{7:2} To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace{7:3} Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually. {7:4} Now consider how great this man [was,] unto whom even the patriarch Abraham gave the tenth of the spoils. {7:5} And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham{7:6} But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.{7:7} And without all contradiction the less is blessed of the better.{7:8} And here men that die receive tithes; but there he [receiveth them,] of whom it is witnessed that he liveth. {7:9} And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham. {7:10} For he was yet in the loins of his father, when Melchisedec met him. {7:11} If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need [was there] that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron? {7:12} For the priesthood being changed, there is made of necessity a change also of the law. {7:13} For he of whom these things are spoken pertaineth to another tribe, of which no man gave attendance at the altar. {7:14} For [it is] evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood. {7:15} And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest, {7:16} Who is made, not after the law of a carnal commandment, but after the power of an endless life. {7:17} For he testifieth, Thou [art] a priest for ever after the order of Melchisedec.
Genesis {14:17} And the king of Sodom went out to meet himafter his return from the slaughter of Chedorlaomer, and ofthe kings that [were] with him, at the valley of Shaveh,which [is] the king’s dale. {14:18} And Melchizedek kingof Salem brought forth bread and wine: and he [was] thepriest of the most high God. {14:19} And he blessed him,and said, Blessed [be] Abram of the most high God,possessor of heaven and earth: {14:20} And blessed be themost high God, which hath delivered thine enemies into thyhand. And he gave him tithes of all. {14:21} And the kingof Sodom said unto Abram, Give me the persons, and takethe goods to thyself. {14:22} And Abram said to the king ofSodom, I have lift up mine hand unto the LORD, the mosthigh God, the possessor of heaven and earth, {14:23} That Iwill not [take] from a thread even to a shoelatchet, and that Iwill not take any thing that [is] thine, lest thou shouldestsay, I have made Abram rich: {14:24} Save only that whichthe young men have eaten, and the portion of the men whichwent with me, Aner, Eshcol, and Mamre; let them take theirportion.
Psalm 110A Psalm of David.{110:1} The LORD said unto my Lord, Sit thou at my right hand, until Imake thine enemies thy footstool.{110:2} The LORD shall send the rod of thy strength out of Zion: rulethou in the midst of thine enemies.{110:3} Thy people [shall be] willing in the day of thy power, in thebeauties of holiness from the womb of the morning: thou hast thedew of thy youth.{110:4} The LORD hath sworn, and will not repent, Thou [art] a priestfor ever after the order of Melchizedek.{110:5} The Lord at thy right hand shall strike through kings in theday of his wrath.{110:6} He shall judge among the heathen, he shall fill [the places]with the dead bodies; he shall wound the heads over manycountries.{110:7} He shall drink of the brook in the way: therefore shall he liftup the head.
Hebrews{7:18} For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. {7:19} For the law made nothing perfect, but the bringing in of a better hope [did;] by the which we draw nigh unto God. {7:20} And inasmuch as not without an oath [he was made priest: ]{7:21} (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou [art] a priest for ever after the order of Melchisedec:) {7:22} By so much was Jesus made a surety of a better testament. {7:23} And they truly were many priests, because they were not suffered to continue by reason of death: {7:24} But this [man,] because he continueth ever, hath an unchangeable priesthood. {7:25} Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them. {7:26} For such an high priest became us, [who is] holy, harmless, undefiled,separate from sinners, and made higher than the heavens; {7:27} Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people’s: for this he did once, when he offered up himself. {7:28} For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, [maketh] the Son, who is consecrated for evermore.
