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.” 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. The Lord knows your needs. When you ask with honesty and real intent, He will prompt you to do that which will increase your ability to act in faith. With consistent practice, faith will become a vibrant, powerful, uplifting, inspiring force in your life. As you walk to the boundary of your understanding into the twilight of uncertainty, exercising faith, you will be led to find solutions you would not obtain otherwise. I testify that I know that is true.
