Every good and perfect gift comes from the Father of Light, who is no respecter of persons and in whom there is no variableness, nor shadow of turning. To please him we must not only worship him with thanksgiving and praise, but render willing obedience to his commandments. By so doing he is bound to bestow his blessings; for it is upon this principle (obedience to law) that all blessings are predicated. — Joseph F. Smith, Improvement Era, Vol. 21, December, 1917
