On a starry night, God appeared before Abraham and promised him that he and his wife would have a son. “I will bless her with a son,” said God, .,she will become the mother of nations and kings.”
One day, Abraham was sitting by the door of his tent. He saw three men standing in the hot sun. He ran and greeted them with a bow and invited them for lunch. He told Sarah to make the best bread she could and picked a young calf from his herd and ordered his servant to prepare that for his guests. When the meal was prepared, Abraham served the three strangers with the best of courtesies and the best of food he had.
The three men asked Abraham about his wife. Abraham told them that she was inside the tent. “Nine months from now, I will come back and your wife Sarah will have a son,” said one of the strangers. Hearing this, Sarah laughed at what the stranger said, for she was too old to give birth to a child.
“Why did Sarah laugh?” asked the stranger who was God himself. “Is anything too hard for the Lord? I promise you, nine months from now you will have a son.” Miraculously, nine months later Sarah did have a son and Abraham named his son Isaac. The word ‘Isaac’ means ‘laughter’.
God fulfils his promise. Sarah gives birth to a child. Abraham names his son, Isaac. The woed ‘Isaac’ means ‘laughter’.
