1Foolish Galatians, who has bewitched you not to obey the truth, before whose eyes Jesus Christ was openly portrayed among you as crucified? 2I just want to learn this from you: Did you receive the Spirit by the works of the law, or by hearing of faith? 3Are you so foolish? Having begun in the Spirit, are you now completed in the flesh? 4Did you suffer so many things in vain, if it is indeed in vain? 5He therefore who supplies the Spirit to you and does miracles among you, does he do it by the works of the law, or by hearing of faith? 6Even so, Abraham “believed God, and it was counted to him for righteousness.” 7Know therefore that those who are of faith are children of Abraham. 8The Scripture, foreseeing that God would justify the Gentiles by faith, preached the Good News beforehand to Abraham, saying, “In you all the nations will be blessed.” 9So then, those who are of faith are blessed with the faithful Abraham.
10For as many as are of the works of the law are under a curse. For it is written, “Cursed is everyone who doesn’t continue in all things that are written in the book of the law, to do them.” 11Now that no man is justified by the law before God is evident, for, “The righteous will live by faith.” 12The law is not of faith, but, “The man who does them will live by them.”
13Christ redeemed us from the curse of the law, having become a curse for us. For it is written, “Cursed is everyone who hangs on a tree,” 14that the blessing of Abraham might come on the Gentiles through Christ Jesus, that we might receive the promise of the Spirit through faith.
15Brothers, speaking of human terms, though it is only a man’s covenant, yet when it has been confirmed, no one makes it void or adds to it. 16Now the promises were spoken to Abraham and to his offspring. He doesn’t say, “To descendants”, as of many, but as of one, “To your offspring”, which is Christ. 17Now I say this: A covenant confirmed beforehand by God in Christ, the law, which came four hundred thirty years after, does not annul, so as to make the promise of no effect. 18For if the inheritance is of the law, it is no more of promise; but God has granted it to Abraham by promise.
19Then why is there the law? It was added because of transgressions, until the offspring should come to whom the promise has been made. It was ordained through angels by the hand of a mediator. 20Now a mediator is not between one, but God is one.
21Is the law then against the promises of God? Certainly not! For if there had been a law given which could make alive, most certainly righteousness would have been of the law. 22But the Scripture imprisoned all things under sin, that the promise by faith in Jesus Christ might be given to those who believe.
23But before faith came, we were kept in custody under the law, confined for the faith which should afterwards be revealed. 24So that the law has become our tutor to bring us to Christ, that we might be justified by faith. 25But now that faith has come, we are no longer under a tutor. 26For you are all children of God, through faith in Christ Jesus. 27For as many of you as were baptized into Christ have put on Christ. 28There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus. 29If you are Christ’s, then you are Abraham’s offspring and heirs according to promise.
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]
