Abraham's name was Abram at first, but God changed it to Abraham. Abraham was from the 20th generation on the earth. When Abraham was 75 years old, God told Abraham to leave his father's house and go to live in a land that God would show him. That land was called Canaan. God promised that He would give that land to Abraham and his seed (child) forever. God told Abraham that He would make him a great nation and bless him. That land is also called Israel and that is why Israel is called the Promised Land. God tested Abraham's love for Him by telling him to sacrifice his son Isaac. When God saw that Abraham's love for Him was so great that he would even kill his son for Him, God told Abraham to let Isaac live.
