You can learn to use faith more effectively by applying this principle taught by Moroni. Faith is things which are hoped for and not seen. Wherefore, dispute not because you see not, for you will receive no witness until after the trial of your faith. Thus, every time you try your faith, that is, act in worthiness on an impression, you will receive the confirming evidence of the Spirit. Those feelings will fortify your faith. As you repeat that pattern, your faith will become stronger.
