And since we have the same spirit of faith, according to what is written, “I believed and therefore I spoke,” we also believe and therefore speak,

For assuredly, I say to you, whoever says to this mountain, ‘Be removed and be cast into the sea,’ and does not doubt in his heart, but believes that those things he says will be done, he will have whatever he says. Therefore I say to you, whatever things you ask when you pray, believe that you receive them, and you will have them.

So then faith cometh by hearing, and hearing by the word of God.
