It was 25 years from the time that Abraham began to obey God's instructions until the promised son was born. He started to do what God told him when he was 75 years old and Issac was born when he was 100. During that time Abraham made some mistakes and bad decisions - much like us when we are trying to follow what God has told us to do and receive His promises. Learn what God did to help Abraham get to the point of faith to receive the promise.
