Isaac is Born
Isaac was born exactly when God said he would be. A year prior, God visited Abraham’s camp and promised they would have a son. Sarah doubted the promise that she would have a child at her age, laughing. God responded to her, saying, "Is anything too difficult for the LORD? At the appointed time I will return to you, at this time next year, and Sarah will have a son" (Genesis 18:14). Just as God said, Isaac was born a year later. Abraham called the name of his son…Isaac, in obedience to God (Genesis 17:17-19). The name Isaac in Hebrew is Yitzhak and means "he laughs" or "laughter." This was because Abraham laughed when God told him he would have a son with his wife, just as she laughed when she learned the same promise. It seemed preposterous that they would ever have children, especially now that they were very old. Yet their laughter, once doubtful, becomes the laughter of joy at finally having a child together. Isaac was the promised son and heir of Abraham. Through Isaac, God would bless the nations and keep His covenant and promises to Abraham (Genesis 21:8-10, 25:1-6). This was the second time Abraham proclaims the name of his baby, the first being Ishmael, and now Isaac (Genesis 16:15). The name Isaac was God’s choice of naming the child Abraham had fathered by Sarah. Isaac’s name was given by God before he was even conceived (Genesis 17:19).
