Rather than choosing someone powerful or famous to begin his family of faith, God calls an ordinary man living in the ancient city of Haran, in modern-day Turkey. Abraham and his wife Sarah have enough means to live comfortably, but they had never been blessed with a child, and now they are far past childbearing years.
God tells him, “Go forth from your land, your relatives, and from your father’s house to a land that I will show you.” (Gen 12:1) This new land would be Canaan, hundreds of miles away to the south. God then makes Abraham three amazing promises.
God promises, “I will make you into a great nation, and I will bless you.” (Gen 12:2) By this, Abraham understands that God is promising that he and Sarah would conceive in their old age, and that their descendants would be so numerous that they would one day form an entire nation. Since every nation needs its own land, God promises Canaan to Abraham and his descendants.
God promises, “I will make your name great, and you will be a blessing.” (Gen 12:2) In biblical terminology, this is not just a promise to have a famous name or be greatly esteemed by others. Rather, it means a dynasty will come from Abraham’s descendants, a line of kings who will rule over other nations.
God promises, “All peoples on earth will be blessed through you.” (Gen 12:2) This means that the blessings poured out upon Abraham will not only benefit Abraham and his descendants. Rather, somehow God will bless the entire world through the family begun by Abraham and Sarah.
He leaves his homeland with Sarah, his relatives, and all those in his household, and together they begin the long journey south. God helps Abraham through different trials, and after many years he gives Abraham and Sarah the miraculous blessing of a son, Isaac. On various occasions, God tests Abraham’s faith and then solemnly reaffirms his promises to Abraham. Abraham and his descendants were meant to be a special people chosen by God.
The entire rest of the Bible is the story of God gradually fulfilling the three promises he made to Abraham in Genesis 12. We will see Abraham’s family slowly grow into a family comprised of twelve tribes. Under Moses, these twelve tribes will become a nation. Under King David, the nation will become a dynasty. And centuries later, Abraham’s family will become a blessing for all the nations.
