Genesis 12 is a pivotal statement of the covenant because it contains God's first recorded speech to Abraham. There God promises to make Abraham a great nation, to bless him, and to make his name great. Genesis 15 makes clear that the LORD took upon Himself alone the responsibility for fulfilling the covenant.
And when Paul picks that up, he sees that fulfilled in Jesus Christ. So, is the Abrahamic covenant still in operation? It is still in operation in the sense that it has been fulfilled. The promise has been realized, and God has kept the promise that He gave to Abraham.
Giving the Covenant Promise: the Call of Abram (Genesis 12) Making the Covenant: the Promise of Descendants and Land (Genesis 15) Affirming the Covenant: the Sign of Circumcision (Genesis 17) Confirming the Covenant: Abraham's Obedience and Confirmation of the Promises by Oath (Genesis 22)
The answer to the question, "How do we enter into the New Covenant" is that we give Jesus permission to enter our lives as Lord and Master. For a person who is not a Christian this means beginning the Christian life by coming to Jesus with the simple trust of a child--inviting God to act.
The book of Genesis includes a number of promises by God to Abraham paired with actions by Abraham, notably in Genesis 12, 15, 17, and 22. Only the promises of Genesis 15 ("covenant of the pieces") and Genesis 17 ("covenant of circumcision") are referred to in the text by the term "covenant" (brit).
An Unconditional Promise The promises that God gave to Abraham (Genesis –3) do not require any righteous actions on Abraham's part and are unconditional in nature.
We typically think of the Abrahamic covenant blessings as “the three P's”: priesthood, posterity, and promised land. Adding these blessings together, they represent the fullness of Heavenly Father's blessings in time and eternity.
The famed Abrahamic covenant comes from Genesis -3. It reads: “Now the Lord said to Abram, 'Go from your country and your kindred and your father's house to the land that I will show you. And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing.
What Do We Learn about God from the Abrahamic Covenant? God's covenant with Abraham shows God's faithfulness. As 2 Timothy says, “If we are faithless, He remains faithful, for He cannot deny Himself.” It shows God does the work and our part is faith.
The covenant between Abraham and God consisted of three separate parts: the promised land. the promise of the descendants. the promise of blessing and redemption.
