11 What is faith? It is the confident assurance that something we want is going to happen. It is the certainty that what we hope for is waiting for us, even though we cannot see it up ahead. ² Men of God in days of old were famous for their faith.

³ By faith—by believing God—we know that the world and the stars—in fact, all things—were made at God’s command; and that they were all made from things that can’t be seen.^[a]

⁴ It was by faith that Abel obeyed God and brought an offering that pleased God more than Cain’s offering did. God accepted Abel and proved it by accepting his gift; and though Abel is long dead, we can still learn lessons from him about trusting God.

⁵ Enoch trusted God too, and that is why God took him away to heaven without dying; suddenly he was gone because God took him. Before this happened God had said^[b] how pleased he was with Enoch. ⁶ You can never please God without faith, without depending on him. Anyone who wants to come to God must believe that there is a God and that he rewards those who sincerely look for him.

⁷ Noah was another who trusted God. When he heard God’s warning about the future, Noah believed him even though there was then no sign of a flood, and wasting no time, he built the ark and saved his family. Noah’s belief in God was in direct contrast to the sin and disbelief of the rest of the world—which refused to obey—and because of his faith he became one of those whom God has accepted.

⁸ Abraham trusted God, and when God told him to leave home and go far away to another land that he promised to give him, Abraham obeyed. Away he went, not even knowing where he was going. ⁹ And even when he reached God’s promised land, he lived in tents like a mere visitor as did Isaac and Jacob, to whom God gave the same promise. ¹⁰ Abraham did this because he was confidently waiting for God to bring him to that strong heavenly city whose designer and builder is God.

¹¹ Sarah, too, had faith, and because of this she was able to become a mother in spite of her old age, for she realized that God, who gave her his promise, would certainly do what he said. ¹² And so a whole nation came from Abraham, who was too old to have even one child—a nation with so many millions of people that, like the stars of the sky and the sand on the ocean shores, there is no way to count them.

¹³ These men of faith I have mentioned died without ever receiving all that God had promised them; but they saw it all awaiting them on ahead and were glad, for they agreed that this earth was not their real home but that they were just strangers visiting down here. ¹⁴ And quite obviously when they talked like that, they were looking forward to their real home in heaven.

¹⁵ If they had wanted to, they could have gone back to the good things of this world. ¹⁶ But they didn’t want to. They were living for heaven. And now God is not ashamed to be called their God, for he has made a heavenly city for them.

¹⁷ While God was testing him, Abraham still trusted in God and his promises, and so he offered up his son Isaac and was ready to slay him on the altar of sacrifice; ¹⁸ yes, to slay even Isaac, through whom God had promised to give Abraham a whole nation of descendants!

¹⁹ He believed that if Isaac died God would bring him back to life again; and that is just about what happened, for as far as Abraham was concerned, Isaac was doomed to death, but he came back again alive!
