Still the patriarch begged for some visible token as a confirmation of his faith and as an evidence to after-generations that God’s gracious purposes toward them would be accomplished. The Lord condescended to enter into a covenant with His servant, employing such forms as were customary among men for the ratification of a solemn engagement. By divine direction, Abraham sacrificed a heifer, a she-goat, and a ram, each three years old, dividing the bodies and laying the pieces a little distance apart. To these he added a turtledove and a young pigeon, which, however, were not divided. This being done, he reverently passed between the parts of the sacrifice, making a solemn vow to God of perpetual obedience. Watchful and steadfast, he remained beside the carcasses till the going down of the sun, to guard them from being defiled or devoured by birds of prey. About sunset he sank into a deep sleep; and, “lo, a horror of great darkness fell upon him.” Genesis 15:7-18. And the voice of God was heard, bidding him not to expect immediate possession of the Promised Land, and pointing forward to the sufferings of his posterity before their establishment in Canaan. The plan of redemption was here opened to him, in the death of Christ, the great sacrifice, and His coming in glory. Abraham saw also the earth restored to its Eden beauty, to be given him for an everlasting possession, as the final and complete fulfillment of the promise. (PP 137.1) MC VC

As a pledge of this covenant of God with men, a smoking furnace and a burning lamp, symbols of the divine presence, passed between the severed victims, totally consuming them. And again a voice was heard by Abraham, confirming the gift of the land of Canaan to his descendants, “from the river of Egypt unto the great river, the river Euphrates.” Genesis 15:18. (PP 137.2) MC VC

When Abraham had been nearly twenty-five years in Canaan, the Lord appeared unto him, and said, “I am the Almighty God; walk before Me, and be thou perfect.” Genesis 17:1-16. In awe, the patriarch fell upon his face, and the message continued: “Behold, My covenant is with thee, and thou shalt be a father of many nations.” Genesis 17:4. In token of the fulfillment of this covenant, his name, heretofore called Abram, was changed to Abraham, which signifies, “father of a great multitude.” Sarai’s name became Sarah—“princess;” for, said the divine Voice, “she shall be a mother of nations; kings of people shall be of her.” Genesis 17:16. (PP 137.3) MC VC
