22 And Jesus answered them, “Have faith in God.23 Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him.24 Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours.
Romans 10
17 So faith comes from hearing, and hearing through the word of Christ.
