In the epistle to the Hebrew Christians, the apostle Paul states seven times that God has made Christ a High Priest according to the order of Melchizedek. He also makes it clear that no one was ever made perfect by the Levitical priesthood as far as the conscience is concerned, and no sin has ever been forgiven by a priest who descended from Levi (Hebrews 10).
So it was necessary that another Priest should come who could do what the descendants of Aaron could never do. What is the function of a priest? He offers gifts and sacrifices for sin (Hebrews 5). It is through the services of a priest that sins are forgiven, but the Levitical priests could not forgive sin, as we saw in the preceding paragraph. However, no one will go to heaven who has his sins forgiven only.
Do not misunderstand. No one can go to heaven unless their sins are forgiven, but it is necessary that more be done for you than just forgiveness of your sins. In order to go heaven, your sins must be taken away—removed from you completely. The person who has had his sins forgiven is still a sinner even though he has been justified, or forgiven, and is accounted innocent.
The sin itself, the degradation from sin, must be removed. No earthly priest ever has or ever will be able to do this for you, but Jesus can and it must happen if you are to be with Him in heaven.
Paul says that Jesus came to put away sin (Hebrews 9). This is the miracle of salvation that everyone who goes to heaven must have. Only the services of a priest after the order of Melchizedek can do this for you.
No one can be saved by a human priest, that is why Jesus said, “ ‘I am the way, the truth, and the life. No one comes to the Father except through Me.’ ” John 14:6
The Melchizedek priesthood is all powerful and can save any sinner (Hebrews 7:25).
Have you asked Him to save you?
