And, most importantly, we believe and accept as true the reality of the atoning sacrifice of the Redeemer. In summary then, belief is the mental and intellectual acknowledgment, acceptance, and assent that something is true. Belief requires only the mind. Faith grows out of and builds upon belief and produces action. Faith is not merely a positive mental attitude, or a strong will, or a Pollyanna-like approach to significant personal and public problems.
Faith is evidenced in deeds.
And as faith is the principle of action, so the opposite of faith, which we typically refer to as doubt, is the principle of inaction. Thus, if you and I have faith in Christ, we accept and live His teachings and we accept and obey His commandments. Faith in prayer is evidenced in part when we kneel down . More importantly, however, faith is reflected when we get up and work diligently to accomplish that for which we have prayed. Whereas belief requires only the mind, faith ultimately requires all of our mind and all of our heart and all of our might and all of our strength.
