Our High Priest and The New Covenant

 [Christ], in the days of His flesh, when He had offered up prayers and supplications, with vehement cries and tears to Him who was able to save Him from death, and was heard because of His godly fear, though He was a Son, yet He learned obedience by the things which He suffered. And having been perfected, He became the author of eternal salvation to all who obey Him, called by God as High Priest according to the order of Melchizedek" Hebrews 5:7-10.  "...Lay hold of the hope set before us. This hope we have as an anchor of the soul, both sure and steadfast, and which enters the Presence behind the veil, where the forerunner has entered for us, even Jesus, having become High Priest forever according to the order of Melchizedek." Hebrews 6:18-20

"Also there were many priests, because they were prevented by death from continuing. But He, because He continues forever, has an unchangeable priesthood. Therefore [Christ] is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them." Hebrews 7:23-25. "Now this is the main point of the things we are saying: We have such a High Priest, who is seated at the right hand of the throne of the Majesty in the heavens, a Minister of the sanctuary and of the true tabernacle which the Lord erected, and not man." Hebrews 8:1-2

“Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah—  not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they did not continue in My covenant, and I disregarded them, says the Lord. For this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people. None of them shall teach his neighbor, and none his brother, saying, ‘Know the Lord,’ for all shall know Me, from the least of them to the greatest of them. For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more.” Hebrews 8:8-12
