“It was by faith that Abraham obeyed when God called him to leave home and go to another land that God would give him as his inheritance. He went without knowing where he was going. And even when he reached the land God promised him, he lived there by faith—for he was like a foreigner, living in tents. And so did Isaac and Jacob, who inherited the same promise. Abraham was confidently looking forward to a city with eternal foundations, a city designed and built by God.
“It was by faith that even Sarah was able to have a child, though she was barren and was too old. She believed that God would keep his promise. And so a whole nation came from this one man who was as good as dead—a nation with so many people that, like the stars in the sky and the sand on the seashore, there is no way to count them.
“All these people died still believing what God had promised them. They did not receive what was promised, but they saw it all from a distance and welcomed it. They agreed that they were foreigners and nomads here on earth. Obviously people who say such things are looking forward to a country they can call their own. If they had longed for the country they came from, they could have gone back. But they were looking for a better place, a heavenly homeland. That is why God is not ashamed to be called their God, for he has prepared a city for them.”
If you are not familiar with the story of Abraham and Sarah, you can read their story in Genesis 11-25. It’s a long story, but it’s foundational to understanding God’s relationship with his special people. Abraham is considered the father of the Jewish people because in Genesis 12 God called him to a new land and promised to raise up a new people through his family line. The only problem was that Abraham and Sarah had no children. By the time we get to chapter 17, Abraham is 99 years old and they still have no children. They had already tried to figure things out for themselves by having Abraham sleep with Sarah’s servant as a substitute. Not what God had in mind…
I don’t know about you, but it’s pretty hard to keep believing that God has promised you something when everything points to that NOT happening. I don’t doubt God, but I certainly doubt myself. Did I hear that right? Did God really promise that? Maybe I just misunderstood. Sarah went through that journey when she offered up her servant as a possible way to fulfill God’s promise. Yet in today’s passage she is held up as a pillar of faith. Turns out that doubting isn’t the opposite of faith.

Sarah is the perfect example of faith in the midst of doubts. Like me, Sarah doubted her own understanding of the promise but she never doubted God. She was so sure of his promise that she tried to help him out (just in case it was her fault that God wasn’t able to fulfill his promise to her). In the end, Abraham and Sarah died before they got to see the true fulfillment of God’s promise — a blessed nation from their descendants and ultimately the Messiah who would come to rescue the whole world. Imagine Abraham and Sarah’s reaction as they entered into God’s eternal kingdom and the new covenant unfolded before their eyes. That moment when everything makes sense. Don’t worry if you doubt along the way, someday you will get that “aha” moment too.
