Hebrews 11:3

However faith is a way of viewing all of life, what lies ahead as well as what is in the past. It involves accepting God’s viewpoint as He has revealed it in His Word. This extends to how the universe came into being (cf. Hebrews 1:2-3) as well as how it will end.

"Belief in the existence of the world is not faith, nor is it faith when men hold that the world was made out of some preexisting ’stuff.’ (In the first century there were people who did not believe in God but who held to some kind of ’creation.’) But when we understand that it was the Word of God (’God’s command,’ NIV) that produced all things, that is faith." [Note: Morris, p. 114.]

Notice that the writer did not say that God created the universe out of nothing (creation ex nihilo), an idea that the Greeks rejected. [Note: Guthrie, p. 227.] He simply said that the universe did not originate from primal material or anything observable. His description does not rule out creation ex nihilo, but neither does it affirm it. Genesis 1:1-3 and logic seem to indicate that God did indeed create the universe, something visible, out of His word, something invisible.
