For at least 25 years, God had promised Abraham that he would be blessed with a son. God even named him Isaac and said he would be born to Abraham at age 100 and his barren wife Sarah at age 90. To any reasonable person, looking at this aged couple and the startling promise, it surely would be impossible to place any hope in God fulfilling it. But, hoping against hope, Abraham did put his trust in a powerful faithful God who gave him a son by Sarah. Today, like Abraham, we are to have a faith that hopes in Christ who brings salvation and hope of eternal life.
