We must thankfully enjoy the marvelous divine privilege of doing good, and serving the eternal cause of good -- not for fleshly gratification, but for spiritual gratification. There is no law against pleasure and happiness and enjoyment: they are what God intends for man. But they must not be groveling and fleshly and death-tending for man. They must be on the plane of, and in harmony with, eternity. Our pleasures must be pleasures of the Spirit. It is hard to grow up to this, and to leave all the bright baby toys behind us; just as all growing up and leaving behind is hard. But only they who tread this hard path can reach the infinitely greater pleasures of eternal maturity. It means setting out in faith up the sometimes dark and rocky road from perishing pleasures to eternal pleasures: but the light at the summit is always shining brightly to lead us on. The world prefers to live and die with its childish toys.
