He did not come to re-establish, reinforce, reintroduce, reiterate, reaffirm, remain in, or re-institute the law. “For the law was given by Moses, but grace and truth came through Jesus Christ [Jn 1:16].”
Why is this important? Because the law was taught by priests who were from the tribe of Levi. They were known as Levites or Levitical Priests. But Jesus was from the tribe of Judah whose descendants were called Jews. Now Moses, and all 12 Hebrew tribes including Judah descended from Abraham. And yet Abraham gave tithe or 10% of his spoil to Melchizedek because Melchizedek was from a higher order than the law.
Melchizedek had neither beginning of days nor end of life. Likewise in Hebrews 6:20 Jesus is revealed “after the order of Melchizedek.” For example, Jesus said, “before Abraham was I AM [Jn 8:58].” Again Jesus is like Melchizedek for “He ever liveth to make intercession for us [Heb 7:25].” Intercession means Jesus is advocating like our lawyer for our innocence because He paid the penalty for our sin on the cross. The intercessory work of Christ is God’s grace or unmerited favor.
If we trust in our ability to keep the law we will surely perish. Even our righteousness is as filthy rags [Isa 64:6]. If we repent of our sins, seek forgiveness for our sinful nature and trust, or have faith in His grace to save us,we will stand before Him at the Judgment Seat clothed in His righteousness and inherit eternal life.
