“But now He has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises.” – Hebrews 8:6
When sin entered the world through Adam, the human race was in conflict with God the Father and we were in need of a mediator. A mediator is one who brings two parties in conflict to an agreement. Jesus, through His death and resurrection, has become our Mediator. The Bible tells us He has become the Mediator between God and man.
The Mosaic covenant that God made with Israel is known as the “Old” covenant or the “first” covenant. It was a covenant that had stipulations with it. Obey and fear God and receive blessings. Do not obey and you will receive punishment. You can see this in Leviticus chapters twenty and twenty-six, a book of the law. Of course, we know that they were not obedient and judgment did come to the nation of Israel.
The “old” covenant was faulty. Not because God made it faulty but because man did. Man made it faulty through disobedience. The law could not be kept perfectly in every aspect and the Bible tells us that if one law is broken, all of them are broken (James 2:10). But God did not leave it there. He promised a new covenant. He promised a perpetual covenant (Jeremiah 31:31-32; Jeremiah 50:4-5). It would be a covenant that could not be broken because it was not faulty. It was not faulty because it was not based on what man does but what The Man, Jesus Messiah, has done for us on the cross. This covenant was perfect because the sacrifice of Jesus’ life for our sins was perfect and done once for all. The only requirement for man in this new covenant was to accept this free gift.
