Suffering has a purgative place, in the scheme of things. If in the earlier stages of man's growth it tempts him to seek relief in evil courses, in the later stages it presses him to seek out its real cause and final cure. Next it has an educative place for it leads him to analyse experience and learn to understand its lessons. Last it has a redemptive place, for it drives him to confess his weakness and seek mercy, grace, and help.
