Abraham lived in the city of Ur. He had everything except a child. He and his wife prayed for a son for years even though his wife Sarah was Barren (unable to bear children.)
Although they were very old God promised them a son and that Abraham would be the father of many nations
God test Abraham's faith by telling him that there is a far away land that is full of riches and life. Most of his relatives thought he was crazy to go on a journey when you dont even know where to go.
After Abraham had settled in the new land. His wife, Sarah bore a son just like God said. He was named Isaac.
God tested Abraham's faith once again by telling him that he had to sacrafice his only son Issac. Abraham was very upset.
But still he went on with the ritual. Just as he raised his knife to sacrifice him an angel came down and told to stop. The angles promised that his descendants will be a numerous as the stars in the sky
