Jesus is the new Adam (1 Corinthians 15:45) and with His resurrection from the dead He has begun the reformation of the entire cosmos (2 Corinthians 5:17 and Revelation 21:5) which is exactly what the Prophets foretold would happen (Isaiah 11:1-10).
Jesus, being the true Adam that has overcome sin, death, and the devil, is also reversing the curse (Galatians 3:13; Isaiah 53:4-6, 10-12; Romans 5:15-21; 1 Peter 2:24, 3:18) and this also means turning unrighteousness to righteousness, disobedience to obedience.
Here is an example. In Genesis 4:23-24, which I will remind you is just after the fall of Adam and Eve, their exile from the presence of God, and the curses God placed upon His creation because of sin, we have the effects of sin played out in the descendants of Cain. Lamech murders a man, like Cain murdered Abel, and declares that if Cain will be avenged sevenfold if anyone killed him for his sin, then Lamech would be avenged seventy and seven fold. Unrighteousness is clearly on the rise.
Adam and Eve rebelled and from Eve’s womb came forth a thorn, Cain. Cain escalates sin and murders his brother Abel. Lamech, Cain’s descendant, takes two wives which undoes the marital bond of one flesh, and he murders another man. Sin is increasing in the land because Adam’s descendants have been corrupted, polluted, by the sin begun in the Garden. Every human, after Adam and Eve, are born under a curse because of their sinful nature and without God’s restraining hand sin would abound much more than it does.
Now, compare Genesis 4:23-24 with Matthew 18:21-22 . Peter comes to the new Adam and asks about forgiveness. He asks if he should forgive a brother up to seven times, and Jesus responds that he must forgive until seventy and seven fold.
Jesus is restoring righteousness into the world by reversing the curse. The first Adam plunged the world into sin and broke the covenantal bonds of creation, like brothers murdering brothers. Jesus, the new Adam, is re-creating the world in Himself and creating a new race of humanity. In Christ we are no longer in Adam, and therefore we must not live like we are in Adam.
A Christian is not a son of Adam, but a brother of Christ, a son of the Father, a descendant of the new Adam. In Christ, righteousness is demanded and righteousness will come. Jesus undoes what Adam did.
