And we do, we have that high priest. He was made a High Priest forever. The others were just a shadow of things to come. Father knew we would need a new covenant eventually. And he is from the priest line and king line. King of Kings and Lord of Lords.
The high priest was the one that could only go behind the curtain. But after the veil was torn, Christ became that high priest. Meaning we can go straight to the Father through him. You and others miss this obvious symbolism. You and others are going backwards, not forwards.
Hebrews 4:14 "Seeing then that we have a great High Priest, That is passed into the heavens, Jesus the Son of God, let us hold fast our profession."
Hebrews 4:15 "For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin."
Hebrews 4:16 "Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need."
Hebrews 6:20 "Whither the Forerunner is for us entered, even Jesus, made an High Priest for ever after the order of Melchisedec.
Hebrews 7:11 "If therefore perfection were by the Levitical priesthood,
what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?"
Hebrews 7:22 "By so much was Jesus made a surety of a better testament."
