Faith may be genuine and yet prove to be weak in moments of stress and perplexity. A vigorous faith will cling to the promise, and to that alone, trusting entirely to God for its accomplishment. Such was Abram’s faith, except upon three or four brief occasions, throughout a long and eventful life. God had no need of Abram’s devices for the accomplishment of His promise. Trust and obedience alone were required. In complying with Sarai’s rash suggestion, Abram followed in the footsteps of Adam. In both instances the result was suffering and disappointment, and the imagined blessing proved to be a curse. By listening to Sarai’s suggestion Abram created for himself difficulties far reaching in their consequences. There ensued domestic trouble and heartache, and hatred between the future offspring of both wives. Again, in the present day, how bitterly the modern representatives of Sarai’s and Hagar’s descendants, the Jews and the Arabs, have contended for the possession of the Holy Land!

Faithlessly concluding that there was no hope of her bearing children, Sarai decided to follow the practice of her native country in order to provide an heir for the family. The legal codes of Mesopotamia recognized the practice whereby a childless wife might give one of her slaves to her husband and obtain children by means of her, and determined precisely the rights of such offspring. Regulations were needed particularly in the case of a first wife who would bear children after the servant had done so, or when a servant would become overbearing after being honored by giving birth to an heir (see the code of Hammurabi, sections 144-146, 170, 171).
