Chapter Four

When Faith Was Reckoned For Righteousness

Abraham returned to Canaan after God delivered him from the consequences of his deceitfulness in Egypt. By that time God had blessed both Abraham and Lot so abundantly that the land could not sustain their combined herds (Gen. 13). Competition for grass and water created conflict between Abraham and Lotís herdsmen. Seeing the potential for much greater problems, Abraham separated himself from Lot by allowing Lot to migrate in the direction of his choice.

Immediately following the separation, God renewed His promise to Abraham (Gen. 13:14-18). God declared that all the land he saw would belong to his descendants, and that his descendants would be too many to count.

Lotís chosen dwelling place put him in the midst of warring kings (Gen. 14). Their war resulted in the capture of Lot and all his possessions. In a daring, creative maneuver, Abraham liberated Lot and all the spoil the victorious kings had taken.

Abraham: Doubt and Faith

(Genesis 15)

After the liberation of Lot, God appeared to Abraham in a vision. God declared that Abraham had divine protection and that his great reward was certain. Abraham now had grave doubts about Sarah bearing him a son. He knew that if he was without a son, God could give him nothing. Concluding that Sarah could not bear a son, he proposed to God an alternate solution. He requested that God accept Eliezer of Damascus, a servant, as his heir.

Abrahamís request was not some curious invention of his own imagination. The Nuzi Tablets document the practice among the Hurrians, who lived in the vicinity of Haran, of childless couples adopting a slave. The slave functioned as their son and became their heir. Abraham was suggesting a known, practiced solution to a threatening problem.1

God rejected Abrahamís proposal. He declared Abrahamís heir would be from his own body. He also declared that his descendants would be in number as the stars of the heavens.

Upon Godís reassurance, Abraham believed Godís promise. At that point the faith reckoned for righteousness came into existence.

And he (Abraham) believed in Jehovah; and he

(Jehovah) reckoned it to him for righteousness

(Gen.15 :6).

Only when Abraham trusted Godís promise in the face of his own doubts did God reckon Abrahamís faith for righteousness.

It is important to note that nothing had happened concerning Godís promise of an heir. Sarah was barren in Ur. She was barren in Haran. She was barren in the initial travels in Canaan and in Egypt. She was still barren at this time. Nothing physically indicated she had been given the ability to conceive. In fact, God gave no indication that conception was imminent. God simply affirmed that the son would be born. On nothing more than the promise of God, Abraham believed it would happen. He believed God would keep His promise simply because God declared that He would. He trusted God to keep His promise at a time when Abraham had genuine doubt born of deep concern. That is the faith which God reckoned for righteousness.

Sarah: Doubt and Solution

(Genesis 16)

Abrahamís concerns were not Abrahamís alone. Godís promises affected Sarahís life and future as certainly as they affected Abrahamís. Her role in the fulfillment of Godís promises equaled that of Abrahamís. She desired the promised son as fervently as did he. She was as anxious for that son as he was. She had to wrestle with the same fears, uncertainties, and concerns that Abraham felt.

Out of her doubt and concern, she also determined a solution. Whereas Abraham proposed his solution to God, Sarah proposed her solution to Abraham. From Sarahís perspective, she had no son because God had restrained her. Since God had restrained her, she would give Abraham her handmaid, Hagar. Hagar was to conceive a child in Sarahís behalf. The child would then be reckoned as Sarahís and could stand as their heir.

Sarahís solution was not a device of her own imagination.2  The practice of servants bearing children in behalf of their mistresses occurred in other families in the Bible, most notably with Jacobís wives, Rachel and Leah (Gen. 30:1-24). Both the Nuzi Tablets and the Code of Hammurabi document the fact that Sarahís proposal was an accepted practice in the culture of their former homes.

Sarahís decision to provide an heir without Godís promised help proved to be no solution. A son, Ishmael, was born. However, Sarah was obsessed with jealousy of and resentment for Hagar from the time of Ishmaelís conception. The conflict became so unbearable that Hagar even attempted to run away.

Sarahís doubt and concern produced results which distinctly differed from those of Abrahamís doubt and concern. Both Abraham and Sarah concluded that the promised son was not going to be born to them. Both concluded that Godís promises would go unfulfilled because of the lack of an heir. As both looked to the future, their deep concern turned into real doubt. Both felt that the situation still could be rescued if only they could provide an heir through which God could work. Both felt a personal responsibility to devise a means of acquiring an heir independent of Godís promise and action. Both found a personal solution to the problem which each felt was workable. However, Abrahamís doubt became faith upon Godís reassurance, and he abandoned his proposal. Sarahís doubt produced a solution of her own making which resulted in her bitter jealousy and her harsh treatment of Hagar.

Abraham: Faith Triumphs in Doubt

(Genesis 17)

Ishmael was born to Abraham when he was 86 years of age. Thirteen years later at 99 years of age, Abraham received Godís confirmation that He indeed would establish His covenant with Abraham. On this occasion, God reaffirmed the covenant in specific terms. He would multiply Abraham exceedingly. He would make Abraham the father of a multitude of nations. Kings would descend from him. Godís covenant would extend to Abrahamís descendants who would inhabit Canaan as a continuing possession. God would be the God of Abrahamís descendants. As assurance, God renamed Abram ďAbrahamĒ (father of a multitude) and Sarai ďSarahĒ (Princess).

However, Abraham and his descendants must seal this covenant with God with a specific act: every male must be circumcised. Circumcision perpetually would stand as the sign of the covenant. Each descendant and each slave must be circumcised. The uncircumcised male would be cut off from Abrahamís descendants as a covenant violator.

Abraham never had doubted God to the degree which he did on this occasion. He fell on his face and laughed (v. 17). He asked in his heart, ďShall a child be born unto him that is a hundred years old? and shall Sarah, that is ninety years old, bear?Ē (v. 17). Then Abraham pleaded with God to accept Ishmael as his heir. Could doubt be any more complete? He laughed at the idea of their having a child. He declared it to be physically impossible. He regarded Godís promise as so impossible that he pled with God to accept one already born to him.

Godís reply was pointed and specific. Ishmael would not be the heir. Another son to be called Isaac would be born to him of Sarah. Sarah would give birth to Isaac at that same time in one year.

Please carefully note the faith which God reckons for righteousness. When God stopped talking with Abraham, Abraham immediately circumcised Ishmael, every male under his authority, and himself. Why? He placed his trust in Godís assurance. What had changed? Nothing. Was Sarah then pregnant? No, and she would not be for three months. What tangible evidence did Abraham have that God would do as He said? None. In the midst of consuming doubt Abraham believed Godís assurance when God renewed the promise.

Upon confidence in Godís promise alone, Abraham circumcised himself and every male under his control and oversight. Could there be any greater evidence of full trust in Godís promise? Could there be any greater affirmation of acceptance of the covenant? Circumcision is extremely painful. The resulting soreness lasts for days. It wounds one of the most sensitive parts of the human body. It was performed on that occasion (and for many generations after) with little to deaden the pain, little to disinfect the wound, and little to relieve the soreness. It was performed with crude cutting instruments. If grown men had to demonstrate trust in God today by subjecting themselves to such an ordeal, it is likely that the ranks of the church would diminish quickly.

Why did Abraham subject himself and all those men under him to such a painful ordeal? For one reason only: he believed that God would keep his promise. That kind of faith made Abraham righteous before God. It was not the obedience of being circumcised that made him righteous. It was the faith which prompted the circumcision which made him righteous.
