He has not become a priest because of a rule about his family line. He has become a priest because of his powerful life. His life can never be destroyed.
But now you know God. Even better, God knows you. So why are you turning back to those weak and worthless powers? Do you want to be slaves to them all over again?
Some people still follow the basic spiritual powers of the world. But you died with Christ as far as these powers are concerned. So why do you act as if you still belong to the world? Here are the rules you follow.
The law is only a shadow of the good things that are coming. It is not the real things themselves. The same sacrifices have to be offered over and over again. They must be offered year after year. That’s why the law can never make perfect those who come near to worship.
But Jesus became a priest with a promise. God said to him, “The Lord has given his word and made a promise. He will not change his mind. He has said, ‘You are a priest forever.’ ” (Psalm 110:4)
The law appoints as high priests men who are weak. But God’s promise came after the law. By his promise the Son was appointed. The Son has been made perfect forever.
Melchizedek has no father or mother. He has no family line. His days have no beginning. His life has no end. He remains a priest forever. In this way, he is like the Son of God.
But Christ offered himself to God without any flaw. He did this through the power of the eternal Holy Spirit. So how much cleaner will the blood of Christ make us! It washes away our feelings of guilt for committing sin. Sin always leads to death. But now we can serve the living God.
