Genesis 21
As God promised years before, God gave Sarah a son; when Abraham was one hundred years old. She was glad and said, “God hath made me to laugh, so that all that hear will laugh with me.” And his name was Isaac, meaning “hearty laughter.”
The boy grew and the day he was weaned, Abraham made a great feast. That day Sarah saw the son of Hagar, who was perhaps fifteen years old, mocking. So she said to Abraham, “Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac.” Abraham did not like to cast them out, but God said to Abraham, “In all that Sarah hath said unto thee, hearken unto her voice, for in Isaac shall thy seed be called.” God then promised to make Ishmael a great nation also.
So Abraham rose up early in the morning, and took bread, and a bottle of water, and gave it to Hagar, putting it on her shoulder, and sent them away. They wandered in the desert; the water in the bottle was gone, the day was hot, Ishmael was very, very thirsty. He could walk no more, and Hagar could not bear to see her son die of thirst before her eyes, so she put him under a shrub and went away from him, a good way off. While Ishmael was under the shrub, what do you think he did? He cried to God. He was a boy of 14 or 15 years old. Do you think God was willing to hear his cry? Yes. He sent an angel to Hagar to say, “God hath heard the voice of the lad;” and he showed her a well of water. Hagar took the water to Ishmael. God took care of Ishmael, and made him live in the desert where he grew and became an archer.
Remember, “The Lord is nigh unto all them that call upon him, to all that call upon him in truth.” Also, “Whosoever shall call upon the name of the Lord shall be saved.”
