Reading descriptions of faith such as those found in Hebrews 11 may lead a reader to think that faith is a binary attribute that you either have or don’t have. That is not the case.
Faith is not a binary attribute. Faith is a continuous attribute. It exists by degrees. You can have a little, or you can have a lot, or anything in between. This is why faith is described variously as great or weak, sufficient or lacking.
Different people have different amounts of faith. Everyone has some faith. Faith is inseparable from action. All actions happen through faith. Having no faith at all would rob you of the ability to act of your own volition. You would merely be acted upon.
You have yet to meet a single person who has no faith, no matter how evil they may be, and no matter how much of an enemy to God they are. Even Satan is full of faith:
Thou believest that there is one God; thou doest well: the devils also believe, and tremble. (James 2:19)
His faith, like ours and like God’s, is the source of his power. You can’t have power without having faith.
Faith varies in which aspect of the faith cycle it is manifested and in degree. You can have great or small desires, great or small reasons, or great or small actions. In concert, these will determine the greatness or smallness of the outcomes you receive.
Those who are “more faithful in keeping the commandments of the Lord” will be “favored of the Lord,” receiving manifestations of his power such as answered prayers and miracles (see Mosiah 10:13).
For it was by faith that Christ showed himself unto our fathers, after he had risen from the dead; and he showed not himself unto them until after they had faith in him; wherefore, it must needs be that some had faith in him, for he showed himself not unto the world. (Ether 12:7)
Great faith makes it possible to receive great outcomes. For example, the brother of Jared saw the Lord many years before his birth because of his “exceeding faith” (see Ether 3).
