Faith is what makes real the things we hope for. It is proof of what we cannot see. God was pleased with the people who lived a long time ago because they had faith like this. Faith helps us understand that God created the whole world by his command. This means that the things we see were made by something that cannot be seen. Cain and Abel both offered sacrifices to God. But Abel offered a better sacrifice to God because he had faith. God said he was pleased with what Abel offered. And so God called him a good man because he had faith. Abel died, but through his faith he is still speaking. Enoch was carried away from this earth, so he never died. The Scriptures tell us that before he was carried off, he was a man who pleased God. Later, no one knew where he was, because God had taken Enoch to be with him. This all happened because he had faith. Without faith no one can please God. Whoever comes to God must believe that he is real and that he rewards those who sincerely try to find him. Noah was warned by God about things that he could not yet see. But he had faith and respect for God, so he built a large boat to save his family. With his faith, Noah showed that the world was wrong. And he became one of those who are made right with God through faith. God called Abraham to travel to another place that he promised to give him. Abraham did not know where that other place was. But he obeyed God and started traveling because he had faith. Abraham lived in the country that God promised to give him. He lived there like a visitor who did not belong. He did this because he had faith. He lived in tents with Isaac and Jacob, who also received the same promise from God. Abraham was waiting for the city that has real foundations. He was waiting for the city that is planned and built by God. Sarah was not able to have children, and Abraham was too old. But he had faith in God, trusting him to do what he promised. And so God made them able to have children. Abraham was so old he was almost dead. But from that one man came as many descendants as there are stars in the sky. So many people came from him that they are like grains of sand on the seashore. All these great people continued living with faith until they died. They did not get the things God promised his people. But they were happy just to see those promises coming far in the future. They accepted the fact that they were like visitors and strangers here on earth. When people accept something like that, they show they are waiting for a country that will be their own. If they were thinking about the country they had left, they could have gone back. But they were waiting for a better country—a heavenly country. So God is not ashamed to be called their God. And he has prepared a city for them.
