Heb 5:1-4  "For every high priest chosen from among men is appointed to act on behalf of men in relation to God, to offer gifts and sacrifices for sins. He can deal gently with the ignorant and wayward, since he himself is beset with weakness.  Because of this he is obligated to offer sacrifice for his own sins just as he does for those of the people.  And no one takes this honor for himself, but only when called by God, just as Aaron was." 


You know, the priests, who entered into the Holy of Holies, needed to cleanse and make sacrifices on behalf of his own sins before entering God's presence. They tied a rope to the ankle of the priest in case his sinfulness remained and he was killed by entering the presence of God unclean. 
You better not decide you're worthy, this meeting with God must not be entered into presumptuously! You want to be humbly answering a calling, walking forward in meekness and submission. 
Jesus, Isa, Yeshua Messiah was said to be a humble person, yet He was the Son of God, the creator of everyone for whom He sacrificed Himself . He ripped the curtain between us and God into and we enter by holding on to His sacrifice on our behalf.


Heb 5:5,6  "So also Christ did not exalt himself to be made a high priest, but was appointed by him who said to him, "You are my Son, today I have begotten you"; as he says also in another place, "You are a priest forever, after the order of Melchizedek." 


Now He is the order of priest not of those who failed, but of "The King of Righteousness" (Melchizedek).  This is a priest like no other-a king of righteousness- a king of peace. This priest-king whom is sacrificed to and give tithes to, who you worship, He is like no other. One only worships God! He is Absolute-One and Only. This is the order of the priesthood of Jesus, He is Yahweh.
Bread represents His body and wine His blood. This is the remembrance of Jesus until He returns to take us to Himself. 


Gen 14:18-20  "And Melchizedek king of Salem brought out bread and wine. (He was priest of God Most High.)  And he blessed him and said, "Blessed be Abram by God Most High, Possessor of heaven and earth; and blessed be God Most High, who has delivered your enemies into your hand!" And Abram gave him a tenth of everything." 

Yet, as our high priest and our propitiation, he humbled Himself fully in reverence to the Father, and He learned from obedience in suffering. 


Heb 5:7,8  "In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to him who was able to save him from death, and he was heard because of his reverence. Although he was a son, he learned obedience through what he suffered." 


Php 2:1-11  "So if there is any encouragement in Christ, any comfort from love, any participation in the Spirit, any affection and sympathy, complete my joy by being of the same mind, having the same love, being in full accord and of one mind. Do nothing from rivalry or conceit, but in humility count others more significant than yourselves.  Let each of you look not only to his own interests, but also to the interests of others. Have this mind among yourselves, which is yours in Christ Jesus who, though he was in the form of God, did not count equality with God a thing to be grasped, but made himself nothing, taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth,  and every tongue confess that Jesus Christ is Lord, to the glory of God the Father." 



Heb 5:9,10  "And being made perfect, he became the source of eternal salvation to all who obey him, being designated by God a high priest after the order of Melchizedek." 


His sacrifice was completed, made perfect in all that He did on our behalf and now His grace to us is applied as a source of eternal salvation. He is Absolute Love. Don't forget to follow humbly in obedience. His love includes absolute justice, He won't be mocked or deceived by those who assume their worthiness.
