The speaker draws a parallel and a comparison between the Covenant that God made with Abraham and the one He made with the nation of Israel. There is a very comprehensive explanation of the desire of God's heart for the Covenant of Israel, and the time of its existence up to the fulfillment of the New Covenant in the New Testament. So it began with Abraham, then the nation of Israel, then through The Son Jesus Christ, but the very purpose of the original Covenant was meant for the entire world and to last for all eternity.
