Spurgeon remarked that those content to be a newspaper editor, a grocer, a doctor or a king rather than become a minister did not possess the fullness of the spirit of God. But doesn't God need solid Christians in these trades and professions as well? Isn't one edging away from the oasis of sound doctrine towards the wastelands of gnosticism by downplaying the needs each of these divisions of labor specialize in addressing? The preacher is going to do you little good if you don't have the physical strength to listen to his message (these needs being met by the grocer and the doctor) and you aren't going to know whether or not it's safe to go to church without the magistrate to keep the bandits at bay and the media to expose when the government has itself become the bandit.
