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. Hebrews 11:1-7 Easy-to-read Version
