Matthew 21:22

Believing; with the faith of miracles granted to them, and under the special teaching of the Holy Ghost, by which they could discern whether a thing was or was not according to the will of God. If they saw that it was not, they would not ask it, or believe that they should receive it. If they saw that it was, and did ask, believing, they would receive it, though it should be as difficult as the removal into the sea of mount Olivet, over which they were then passing.
