It has been a little over 1,000 years from the time of Adam to Abraham. In these Scriptures we see that God was establishing a land (a new place), a what (a new people), a who (a new name), and a when (a continuous future) who will worship Him.
In Gen. 12:1-3 we have what we call the “Abrahamic Covenant”. It is more a covenant of worship from God to man. He was re-establishing relationship with man by making a people from those who were not a people, the Jewish nation, and moving worship from an individual act to a corporate act.
What did Abraham do after the Father spoke the covenant promise? In verse 7 we see that he built an altar and worshipped the Father of promises. Remember that the “altar” represents a place of sacrifice, a place of giving, a place of submission, and a place of one honoring another.
What was God’s response? He appeared to Abraham. This sounds like the relationship that Adam enjoyed before the fall. It involved worship, walking hand-in-hand with God the Father daily in confession, repentance, sacrifice, obedience, and thanksgiving. By the covenant promise that God gave to Abraham He was setting apart a land (the place), setting apart a people (the what), setting apart a name, (the who), and setting apart a future, (the when) for His Divine Presence. When God “sets apart” a land, a people, a name, and a future it means that He declares it “holy for His presence.” God is more committed to (us) a people that will worship Him then we are committed to give Him the act of worship.
