Thematic Bible: What faith is

Now, [having] faith is being sure of [receiving] what is hoped for, and certain [of the existence] of what is not visible. For the men of old [i.e., the forefathers. See 1:1], received [God's] approval [for their faith]. By [having] faith, we understand that the universe was formed by God's word [See Gen. 1:1-27], so that what is seen has not been made out of what is visible.
