Mark 11:22-24

22 And Jesus, answering, said to them, Have God's faith.

23 Truly I say to you, Whoever says to this mountain, Be taken up and be put into the sea; and has no doubt in his heart, but has faith that what he says will come about, he will have his desire.

24 For this reason I say to you, Whatever you make a request for in prayer, have faith that it has been given to you, and you will have it.
