Faith: a complete awareness of a power not discernable by the five senses of the body.
There are two primary levels of faith according to my understanding today.
The Basic Power of Faith
This level of faith starts the process to exaltation. We use this level of faith to obtain a testimony of truth (Lectures On Faith, p. 33). It’s the lowest common denominator discussed in church and at General Conference.
Faith is not a perfect knowledge. (Alma 32:21)
