The promises have yet to be fulfilled, and God continues working to this day (John 5:17;
9:3), because of His commitment to His promises and covenant with Abraham.
When recounting the history of God's people, the Old Testament repeatedly refers to the Abrahamic Covenant as His
promises to Abraham, and as He fulfills those promises, He does so for the sake of His name (Deut 4:32-39;
Abraham's seed, Jesus Christ, is the subject of the New Testament which ends with the future and complete fulfillment
of the Abrahamic Covenant.
Chosen because of his faith, Abraham would serve God by teaching his children "the way of the Lord."
For I have chosen him, so that he may command his children and his household after him to keep the way of the
Lord by doing righteousness and justice, so that the Lord may bring upon Abraham what He has spoken about him.
When Abraham's descendants failed to keep the way of the Lord, God kept His promise to Abraham by making the conditional
covenant with Moses to teach the nation of Israel of what sin was and how to be His own possession
(Ex 19:5-6; 24:3-8;
And when the nation of Israel failed uphold their covenant to keep the way of the Lord, God kept His promise to Abraham
by making the unconditional New Covenant with the descendants of Abraham (Jer 31:31-34;
Ezek 36:17-27; 37:24-28).
