Abraham was the patriarch of Israel. Abraham is a paragon of faith. He lived in a world that regarded family and tribe as security, but the Lord called him to leave his family, people, and country and travel to a different land—and Abraham did so without question!
The land that the Lord was going to give Abraham’s descendants was already well settled, so how could he “inherit” this land? Finally, his wife was in her sixties—well past childbearing years— so how could he ever expect to have any descendants at all (Genesis 12)?
But Abraham trusted God and His promises, and his faith was rewarded. Abraham and Sarah eventually bore Isaac, who fathered Jacob, who fathered the leaders of the twelve tribes of Israel.
Many years later, the Israelites conquered the Promised Land of Canaan and occupied it as their inheritance. God was indeed faithful. Abraham was not without his times of doubt.
For instance, on two separate occasions he lied about his wife in order to protect his life (Genesis 12, 20). Abraham also expressed doubt that he would bear a son to carry on his name and estate (Genesis 15:1–3).
Nevertheless, when the Lord made promises to Abraham, he “believed the LORD, and he credited it to him as righteousness” (Genesis 15:6).
While Abraham is certainly a great example of faith for Christians today, that is not all he is to us. We are also his very children, the descendants whom God had promised to give him and to bless. Paul makes this clear in his letter to the Galatians: “Understand, then, that those who believe are children of Abraham” (Galatians 3:7).
Thank God that all His faithful promises are made available even to us who believe Him today.
