'Believed' in the Bible

For what does the scripture say? "And Abraham believed God, and it was credited to him for righteousness."

(just as it is written, "I have made you the father of many nations") before God, in whom he believed, the one who makes the dead alive and who calls the things that are not as [though] they are,

who against hope believed in hope, so that he became the father of many nations, according to what was said, "so will your descendants be."

How then will they call upon [him] in whom they have not believed? And how will they believe [in him] about whom they have not heard? And how will they hear about [him] without one who preaches [to them]?

But not all have obeyed the good news, for Isaiah says, "Lord, who has believed our report?"

And [do] this [because you] know the time, that [it is] already the hour for you to wake up from sleep. For our salvation [is] nearer now than when we believed.
