Covenant can be defined as an agreement between God and man that cannot be broken. Covenant is the framework for all the events in the Bible. The covenants of the Bible come in a consecutive series that logically build upon one another.
1. Adam and Eve - God transfers authority to govern planet earth to men and women (Genesis 1:26). For this reason Yeshua (Jesus) had to be born into the earth as a human being. This was confirmed by the promise that the "seed" of the woman would one day crush the head of the serpent (Genesis 3:15).
2. Noah - The flood of Noah was exponentially more cataclysmic than anyone can imagine. Noah's family was likely terrified. Perhaps the earth would disintegrate under their feet. For this reason God made the "rainbow covenant" that creation would not be destroyed (Genesis 9:11). [This is one reason that the new heavens and new earth of Revelation 21 must be a renewal of creation and not an "un-creating" of the universe.]
3. Abraham - Abraham will be a blessing and a father to the nations through his seed, and will take possession of the land of Canaan (Genesis 12:2-3; 17:2-8). In this covenant, God renews and develops what was promised to both Adam and Noah. Abraham, like Adam and Noah, now has authority to repossess planet earth (Romans 4:13). The seed that will defeat the serpent will come through Abraham. The nations that were born from Noah will be blessed through him.
4. Judah - The promise of the coming seed is then continued from Abraham to Judah (Genesis 49:10). This is one reason the Jewish people cannot be destroyed (Jeremiah 31:36-37) and that they must be part of inviting Yeshua back to earth to rule and reign (Matthew 23:39).
5. Moses - The people of Israel make an unbreakable vow to keep all the perfect moral commandments of Sinai. But then they break the Law. They are doomed. This is a terrifying situation. This is the background for the need of a new covenant (Jeremiah 31:31-33). The Jewish people have broken their own covenant and need to be redeemed - which would be impossible without supernatural intervention.
6. David - God makes an unbreakable covenant with David that his seed will reign on the earth from Jerusalem forever (Psalm 89:3-4, 28-29, 34-37). This is one reason why the 2nd Coming of Yeshua must be literal and that Yeshua will reign on the earth in the millennial kingdom from Jerusalem. It's not only a question of end times' prophecy but of God's faithfulness to His covenants.
7. Yeshua - God is not a liar. The New Covenant takes into consideration all the previous promises of God. Through Yeshua as the Son of Adam, God's delegated authority over planet earth will be restored. Along with Yeshua's resurrection, the planet that God promised to Noah to preserve will also be restored (Romans 8:19-22; Matthew 19:28; II Peter 3:4-13). All the nations are blessed through Yeshua as Abraham's seed (Galatians 3:13). The Jewish people are preserved, the sins of breaking the Law are forgiven, and David's kingdom will be restored on the earth (Luke 1:32-33; Acts 1:6).
God's covenants are unbreakable. All God's promises will be fulfilled. We are saved, not by a philosophical agreement, but by a covenantal commitment. The covenant is offered to us by grace. Our faith is a partnership with God in a covenant agreement that cannot be broken.
