think there is a difference between happiness and joy. Happiness is
caused by things which happen around me, and circumstances will mar
it, but joy flows right on through trouble; joy flows on through the
dark; joy flows in the night as well as in the day; joy flows all through
persecution and opposition; if flows right along, for it is an unceasing
fountain bubbling up in the heart; a secret spring which the world can't
see and don't know anything about; but the Lord gives His people perpetual
joy when they walk in obedience to Him."
