Richard G. Scott gave us a pattern for strengthening our faith. He said,

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 ye see not, for ye receive no witness until after the trial of your faith.” [ Ether 12:6; emphasis added.] 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.”
