Genuine, authentic faith must be definite and free from doubt. It is not general in character or a mere belief in the being, goodness and power of God. It is a faith that believes that the things that “he says will be done” (Mark 11:23).

As faith is specific, so the answer will also be definite. “He will have whatever he says” (v. 23). Faith and prayer select the things, and God pledges Himself to do the very things that faith and persistent prayer name and ask Him to accomplish.

We might also translate Mark 11:24 this way: “All things whatsoever you pray and ask for, believe that you receive them, and you shall have them.” Perfect faith always has in its keeping what perfect prayer asks for. How large and unqualified this area of operation is—“all things whatsoever”! How definite and specific the promise is—“you shall have them”!
