1But I say that so long as the heir is a child, he is no different from a bondservant, though he is lord of all, 2but is under guardians and stewards until the day appointed by the father. 3So we also, when we were children, were held in bondage under the elemental principles of the world. 4But when the fullness of the time came, God sent out his Son, born to a woman, born under the law, 5that he might redeem those who were under the law, that we might receive the adoption as children. 6And because you are children, God sent out the Spirit of his Son into your hearts, crying, “Abba, Father!” 7So you are no longer a bondservant, but a son; and if a son, then an heir of God through Christ.
8However at that time, not knowing God, you were in bondage to those who by nature are not gods. 9But now that you have come to know God, or rather to be known by God, why do you turn back again to the weak and miserable elemental principles, to which you desire to be in bondage all over again? 10You observe days, months, seasons, and years. 11I am afraid for you, that I might have wasted my labor for you.
12I beg you, brothers, become as I am, for I also have become as you are. You did me no wrong, 13but you know that because of weakness in the flesh I preached the Good News to you the first time. 14That which was a temptation to you in my flesh, you didn’t despise nor reject; but you received me as an angel of God, even as Christ Jesus.
15What was the blessing you enjoyed? For I testify to you that, if possible, you would have plucked out your eyes and given them to me. 16So then, have I become your enemy by telling you the truth? 17They zealously seek you in no good way. No, they desire to alienate you, that you may seek them. 18But it is always good to be zealous in a good cause, and not only when I am present with you.
19My little children, of whom I am again in travail until Christ is formed in you— 20but I could wish to be present with you now, and to change my tone, for I am perplexed about you.
21Tell me, you that desire to be under the law, don’t you listen to the law? 22For it is written that Abraham had two sons, one by the servant, and one by the free woman. 23However, the son by the servant was born according to the flesh, but the son by the free woman was born through promise. 24These things contain an allegory, for these are two covenants. One is from Mount Sinai, bearing children to bondage, which is Hagar. 25For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children. 26But the Jerusalem that is above is free, which is the mother of us all. 27For it is written,
“Rejoice, you barren who don’t bear.
Break out and shout, you who don’t travail.
For the desolate women have more children than her who has a husband.”
28Now we, brothers, as Isaac was, are children of promise. 29But as then, he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now. 30However, what does the Scripture say? “Throw out the servant and her son, for the son of the servant will not inherit with the son of the free woman.” 31So then, brothers, we are not children of a servant, but of the free woman.
We first encounter Abraham (father of many nations) as Abram (great father) in Genesis 11:26-31). He was the son of Terah, brother of Nahor and Haran, and uncle of Lot. Abram's brother Haran died while Abram was still in Ur of the Chaldees (Gen 11:28), where also he married Sarai, his half-sister. We discover toward the end of Genesis 11 that his father Terah left Ur, and went to the land of Canaan, via a city named Harana, where Terah died.
The story of Abraham becomes important in chapter 12, in which we are introduced to important biblical characters, locations, and events that set the stage for the remainder of the Bible. Yahweh came to Abram was commanded him to go to a land that He would show him. In this passage, Yahweh sets forth and unilateral and unconditional covenant, in which He promised to make from him a great nation, make his name great, and through him bless all of the families of the earth.[1]
"Abraham (Abram) was first of the patriarchs, father of Isaac and Ishmael, grandfather of Jacob and the traditional ancestor of the Jewish people. Abraham (originally Abram, which means "exalted father") came from Ur in Mesopotamia. His father, Terah, took him (with his wife, Sarah, and his nephew, Lot) to Haran. God called Abraham to leave this new home and to find another home elsewhere in Canaan. After a brief stay in Egypt, Abraham settled near Hebron where he became involved in a local political quarrel when Lot was taken prisoner by an alliance of four eastern chieftains. Abraham launched a successful attack against this confederacy and on his victorious return encountered the mysterious Melchizedek, king of Salem, to whom he gave a tenth of all the spoil he had taken in the battle.
For many years of their marriage, he and Sarah were childless, but God assured Abraham that he would eventually become the father of a great nation. Sarah disbelieved and persuaded Abraham to beget a child by her maid, Hagar, who bore him his first son, Ishmael. When Abraham was ninety-nine years old, God appeared to him, and instituted with him a covenant of circumcision, giving him the new name of Abraham (meaning "father of a multitude") and told him that a son, to be named Isaac was shortly to be born to Sarah. When the boy was in his childhood, God ordered Abraham to take him up to a mountain in the land of Moriah and offer him up as a sacrificial victim. Abraham prepared to do so, but was prevented at the last moment from carrying out the sacrifice, and told that he would be blessed for his faithfulness in being ready to offer up his son.
When Sarah died Abraham bought the plot of ground (the field of Ephron in Machpelah) that became the burial place for many generations of his descendants. He subsequently made arrangements for the marriage of Isaac, and took another wife, Keturah, who bore him Zimran, Medan, Midian, Ishbak and Shuah. At the age of one hundred and seventy five, Abraham died and was buried in Machpelah.
The principal narrative of the part of Genesis dealing with Abraham's history is interrupted in various places by other stories involving the patriarch. These include the parallel stories of his sojourns in Egypt and in Gerar. On both occasions Abraham lied about his relations with Sarah, jeopardising the fulfilment of God's promise (as both Pharaoh and Abimelech intended to take Sarah for themselves), while protecting himself. Both times God intervened to save him from the consequences of his deception. In another story we read of Abraham's intercession on behalf of the cities of Sodom and Gomorrah, which were destroyed for their wickedness."[2]
