All honey would harm us; all wormwood would undo us – a composition of both is the best way to keep our souls in a healthy constitution.  It is best and most for the health of the soul – that the warm south wind of mercy, and the cold north wind of adversity – do both blow upon it.  And though every wind which blows, shall blow good to the saints; yet certainly their sins die most, and their graces thrive best, when they are under the frigid, drying, nipping north wind of calamity, as well as under the warm, nourishing south wind of mercy and prosperity.
