And Jesus, replying, said to them, Have faith in God [constantly].
Truly I tell you, whoever says to this mountain, Be lifted up and thrown into the sea! and does not doubt at all in his heart but believes that what he says will take place, it will be done for him.
For this reason I am telling you, whatever you ask for in prayer, believe (trust and be confident) that it is granted to you, and you will [get it].
Mark 11:22-24
King David
