Set your affection on things above, not on things on the earth.
Nearly all can recall that favourite fiction of their childhood, the voyage of Sinbad the sailor into the Indian Sea. They will remember that magnetic rock that rose from the surface of the placid waters. Silently Sinbad's vessel was attracted towards it; silently the bolts were drawn out of the ship's side, one by one, through the subtle attraction of that magnetic rock. And when the fated vessel drew so near that every bolt and clamp was unloosed, the whole structure of bulwark, mast, and spars tumbled into ruin on the sea, and the sleeping sailors awoke to their drowning agonies. So stands the magnetic rock of worldliness athwart the Christian's path. Its attraction is subtle, silent, slow, but fearfully powerful on every soul that floats within its range. Under its enchanting spell bolt after bolt of good resolution, clamp after clamp of Christian obligation, are stealthily drawn out. What matters it how long or how fair has been the man's profession of religion, or how flauntingly the flag of his orthodoxy floats from the masthead? Let sudden temptation smite the unbolted professor, and in an hour he is a wreck. He cannot hold together in a tempest of trial, he cannot go out on any cruise of Christian service, because he is no longer held together by a Divine principle within. It has been drawn out of him by that mighty loadstone of attraction, a sinful, godless, self-pampering, Christ-rejecting world.
