Mere pleasure is at best but fleeting; happiness is abiding, for in the recollection thereof is renewed.

Quotes from the same author

Belief is in a sense passive, an agreement or acceptance only; faith is active and positive, embracing such reliance and confidence as will lead to works. Faith in Christ comprises belief in Him, combined with trust in Him. One cannot have faith without belief; yet he may believe and still lack faith. Faith is vivified, vitalized, living belief.
 James E. Talmage
Belief, in one of its accepted senses, may consist in a merely intellectual assent, while faith implies such confidence and conviction as will impel to action.
 James E. Talmage
