Abraham, Isaac, and Jacob are deeply linked to our present work.
Isaac had a baby with his wife when he was sixty. He was married at forty and did not have a baby for twenty years. So became worried that he might never have a baby, because he had heard about the God's words from his father, Abraham. Abraham said to him, “God has been with me for my whole life. He explained to me that my descendents will be his people, so you should marry with whom I arrange for you.” He sent his chief servant to his country to find a bride for Isaac.
Then, Isaac married Rebekah and was expecting lots of children from her. But, to his surprise, he could not have a baby until he was sixty years old. After he had constantly prayed to God for a baby, his wife finally became pregnant. He was so happy about her pregnancy, but she felt something wrong in her womb. Nowadays, if a mother suffers a problem during a pregnancy, doctors would check it and treat it easily. But in the time of Isaac, if there were such complications, both the mother and the baby’s lives would be in danger.
