Christ "Does away with the first in order to establish the second." Christ did away with the first covenant, its priesthood, its temple, and its sacrifices so that he could establish the second. The new covenant is one of grace; the new priesthood is found in Jesus and remains forever, the new temple is the very heaven of God, and the new sacrifice is Jesus. The new was needed because "It is impossible for the blood of bulls and goats to take away sins." Those sacrifices of the Old Testament could not make anyone clean and could not remove sins. And even if those sacrifices were thought to make someone clean from sin, they could not overthrow the power of sin or the guilt associated with it. In contrast to the Old Testament sacrifices, we see that in Jesus, "By a single offering he has perfected for all time those who are being sanctified."
