Do not suppose that by heaven here is meant the upper regions of the sky of this visible world, for your reward is not to be placed in things that are seen, but by “in heaven” understand the spiritual firmament, where everlasting righteousness dwells. Those then whose joy is in things spiritual will even here have some foretaste of that reward; but it will be made perfect in every part when this mortal shall have put on immortality.
