The kingdom of man needed a way to move from the heavily judgmental state of being that is found in the Old Testament. We needed to move to a state of greater availability of grace for our errors. Yes, I know that the LORD has already provided this way, in the modern time: so, who cares about the ancient times?We all should care about the ancient times because we need to clearly understand the method that was used, and, to a lesser degree, the reason that the movement was required. We need to convince our minds that we must possess the transport of God that moves us from condemnation and continual earth-centric actions for the procurement of forgiveness. In other words, we need to move our focus away from external excuses; such as the one that existed in the time when it was up to the priests to make amends for our individual sins. The transformation in the reality and practice of righteous intervention for our soul’s sake, in our interaction with God the Father, is explained in a sermon of the apostle Paul.
Sacrifice and offering thou wouldest not, but a body hast thou prepared me: In burnt offerings and sacrifices for sin thou hast had no pleasure. Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.
Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law; Then said he, Lo, I come to do thy will, O God.
He taketh away the first, that he may establish the second. By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; From henceforth expecting till his enemies be made his footstool. For by one offering he hath perfected for ever them that are sanctified.
