But now Jesus has obtained a ministry that is as far superior [to that of the Levitical priesthood] as the [New] Agreement, of which He is the Mediator, is better [than the old one], because it has been enacted on better promises.
So, if perfection [i.e., a right relationship with God] could have been attained through the Levitical priesthood, (for under it people had received the law of Moses), what further need would there have been for another priest to arise, according to the order of Melchizedek, who was not considered "according to the order of Aaron"?
Is the law of Moses contrary to the promises of God? Certainly not! For if there had been a law given which could provide [never ending] life, then a person could be considered right with God by [obeying the requirements of such] a law.
