Doctrine and Covenants 10: 46-52

"And, behold, all the remainder of this work does contain all those parts of my gospel which my holy prophets, yea, and also my disciples, desired in their prayers should come forth unto this people.

"And I said unto them, that it should be granted unto them according to their faith in their prayers;

"Yea, and this was their faith—that my gospel, which I gave unto them that they might preach in their days, might come unto their brethren the Lamanites, and also all that had become Lamanites because of their dissensions.

"Now, this is not all—their faith in their prayers was that this gospel should be made known also, if it were possible that other nations should possess this land;

"And thus they did leave a blessing upon this land in their prayers, that whosoever should believe in this gospel in this land might have eternal life;

"Yea, that it might be free unto all of whatsoever nation, kindred, tongue, or people they may be.

"And now, behold, according to their faith in their prayers will I bring this part of my gospel to the knowledge of my people. Behold, I do not bring it to destroy that which they have received, but to build it up."

 Faith.

Doctrine and Covenants 90:24 "Search diligently, pray always, and be believing, and all things shall work together for your good, if ye walk uprightly and remember the covenant wherewith ye have covenanted one with another."

James 1:5-6 "If any of you lack wisdom, let him ask of God, that giveth to all men liberally and abraideth not; and it shall be given him. But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed."

The Apostle Paul taught that "faith is the substance [assurance] of things hoped for, the evidence of things not seen" (Hebrews 11:1). Alma made a similar statement: "If ye have faith ye hope for things which are not seen, which are true" (Alma 32:21). Faith is a principle of action and power. Whenever we work toward a worthy goal, we exercise faith. We show our hope for something that we cannot yet see.
