Promises to Abraham

Abraham was a pilgrim and stranger in the promised land all his days. He believed the promise of God that his descendents would possess this land, even into old age when it seemed that all hope of having children was slipping away from him. God told him: “Arise, walk through the land in the length of it and in the breadth of it; for I will give it unto thee” (Genesis 13:17).

When Abram decided that the only heir he would ever had would be the son of his servant who was born in his house, God spoke to him again. “ This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir. And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be. And he believed in the LORD; and he counted it to him for righteousness” (Genesis 15:4-6).

Sarah, Abraham’s wife, wanted him to have a son in fulfilment of God’s promise. She had no child and was past normal child-bearing age, so she gave her servant Hagar to Abraham as was the custom of the day. This worked, Ishmael was born and Abraham now had a son who was his own flesh and blood. But this was still not the heir that God had promised to Abram.

When Abram was 90 years old God renewed His promise and made a covenant with Abram, changing his name to Abraham, father of a multitude. “ And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee” (Genesis 17:7). It was at this point that circumcision was made the sign of the covenant.

Abraham was 100 years old and Sarah 90 or 91 when Isaac, the son of the promise was born. Their faith had been tested for many years, but now they could see the beginning of God’s promise of a multitude of nations as their direct descendents.
God had yet one more test for Abraham. He told him to go up to the top of Mount Moriah and there offer his son as a sacrifice to God. Isaac could not have been a small child by this time, probably more like 20. Josephus says 25. Isaac carried the wood for the sacrifice to Mount Moriah and up the mountain, not something a small child could have done. This leads us to believe that Isaac shared his father’s faith, for he must have fully cooperated when Abraham bound him and laid him on the altar.

Abraham took the knife in his hand and raised it. At this point God stopped his hand and said, “now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me” (Genesis 22:13). In the providence of God, now Abraham saw a ram caught in a thicket and offered him on the altar in place of his son.

“And the angel of the LORD called unto Abraham out of heaven the second time, and said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thine only son: that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies; and in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice” (Genesis 22:15-18).

There is so much for us bound up in the story of Abraham. Like him, we have been given an heritage. This heritage is revealed in the pages of the Bible and it is up to us to walk through the length and breadth of those pages to grasp all that God has is store for us.

Abraham believed God’s promise that he would have an abundance of heirs; that faith was counted to him for righteousness long before he received the covenant of circumcision. As the apostle Paul explains in Romans 4:9-14, this demonstrates that the promise to Abraham is to the uncircumcised as well as the circumcised. In another place the apostle explains that the circumcision that counts is the inward circumcision of the heart, not the outward form. All who are circumcised in heart by faith are then heirs of Abraham.

The New Testament also explains that the promise to Abraham is not for the children of the flesh, typified by Ishmael, but for the spiritual descendents of the son of promise.

Finally we have the picture of a father preparing to offer his only son as a sacrifice. In the New Testament we have the awful picture of the only Son of God dying on the cross as an offering for our sin. The ram that Abraham offered on the altar in place of his son is another piece of the great salvation story that God has provided a spotless Lamb to be sacrificed that He could forgive us and set us free.
Here, very early in Bible history, God has provided a complete picture of the whole salvation story through the events in the life of Abraham.
