These questions look difficult enough. Let us attempt to answer them.
Pleasure and pain, happiness and suffering, are elements of creaturely experience appointed by God. The right use of them makes life, the wrong use of them mars it. They are ordained, all of them in equal degree, to a good end; for all that God does is done in perfect love as well as in perfect justice. It is no more wonderful that a good man should suffer than that a bad man should suffer; for the good man, the man who believes in God and therefore in goodness, making a right use of suffering, will gain by it in the true sense; he will reach a deeper and nobler life. It is no more wonderful that a bad man, one who disbelieves in God and therefore in goodness, should be happy than that a good man should be happy, the happiness being God's appointed means for both to reach a higher life. The main element of this higher life is vigour, but not of the body. The Divine purpose is _spiritual_ evolution. That gratification of the sensuous side of our nature for which physical health and a well-knit organism are indispensable--paramount in the pleasure-philosophy--is not neglected, but is made subordinate in the Divine culture of life. The grace of God aims at the life of the spirit--power to love, to follow righteousness, to dare for justice' sake, to seek and grasp the true, to sympathise with men and bear with them, to bless them that curse, to suffer and be strong. To promote this vitality all God appoints is fitted--pain as well as pleasure, adversity as well as prosperity, sorrow as well as joy, defeat as well as success. We wonder that suffering is so often the result of imprudence. On the ordinary theory the fact is inexplicable, for imprudence has no dark colour of ethical faultiness. He who by an error of judgment plunges himself and his family into what appears irretrievable disaster, may, by all reckoning, be almost blameless in character. If suffering is held to be penal, no reference to the general sin of humanity will account for the result. But the reason is plain. The suffering is disciplinary. The nobler life at which Divine providence aims must be sagacious no less than pure, guided by sound reason no less than right feeling.
