Noah, Abraham, and Elijah represent the three main heroes of faith in The Old Testament. Each demonstrates his faith in God by performing seemingly irrational tasks after God has been absent from humankind for an extended period of time. God has not spoken to humans for many generations when Noah obediently builds a large, strange boat in preparation for a monumental flood. Abraham similarly dismisses the idols and gods of his region in favor of a belief that an unseen and unnamed deity will provide a promised land for his descendants. Centuries later, the prophet Elijah attempts to rejuvenate faith in God after Israel has worshipped idols for decades. Like Noah and Abraham, Elijah develops a faith based on his ability to communicate directly with God.
