Through faith Abel offered God a better sacrifice than Cain, and so received the assurance that he was an upright man, for God approved of his gifts. Though dead, yet because of his faith he still speaks. Through faith Noah, having been told by God about things still unseen, in reverent obedience built an ark to save his household; and in doing so he condemned the world and became heir to the righteousness that comes through faith. Through faith Abraham obeyed, when he was called to go to the place which he was to receive as an inheritance, and he set out, not knowing where he was going. Through faith he made his home in the land that had been promised to him as in a foreign country, living in tents with Isaac and Jacob, who shared the same promise with him. Through faith Abraham, when put to the test, sacrificed Isaac, yes, was ready to sacrifice his only son, although he had received the divine promises and had been told, "It is through Isaac that your family name will be carried on," for he believed that God was able to raise men even from the dead. In a sense, he did receive his son back from the dead. Through faith, also, Isaac blessed Jacob and Esau, even telling them of things to come. Through faith Joseph, as he was dying, thought of the time when the Israelites would go out of Egypt and gave orders about his own bones. Through faith Moses was hidden by his parents for three months after birth because they saw that the child was beautiful, and because they did not fear the King's command. Through faith Moses, when he had grown up, refused to be called the son of Pharaoh's daughter, choosing rather to share ill treatment with God's people than to enjoy for a short time the pleasures of sin. Through faith he left Egypt, not because he feared the King's wrath, but like one who saw the Unseen King he never faltered. Through faith the Israelites crossed the Red Sea as through dry land, and when the Egyptians tried to cross they were drowned. What more shall I say? For time would fail me if I tried to tell of Gideon and Barak and Samson and Jephthah, of David and Samuel and the prophets--they who through faith conquered kingdoms, did righteous acts, received promises from God, closed the mouths of lions, quenched the power of fire, escaped the edge of the sword, in the hour of weakness were made strong, who proved mighty in war and put to flight foreign armies!
