When Abram was 99 years old, God appeared to him and spoke. God told Abram to live a holy life and obey Him. God made a special promise called a covenant. A covenant is like an agreement or promise between God and His people. God promised to be Abraham’s God and to give him many descendants, so many that they could not be counted.
God also said that Abraham would be the father of nations and kings. Abraham would have a special son through whom God’s plan for blessing the world would continue. God changed Abram’s name to Abraham, which means “father of many nations,” to show this promise. Sarai, Abraham’s wife, also received a new name: Sarah, which means “princess.” God promised that she would have a son, even though she was very old.
