Robert Hall once said that if two angels were sent down from heaven, one to sweep the streets of London and the other to be its lord mayor, they would not debate on the way the question, Which is the greater honor? All men are to be equally honored who equally fulfill their duty, whether to rock a cradle or to command the army at Gettysburg.
But to do as the God-man did when he preached up and down Galilee and Judea seems to be the most exalted occupation to which mortals can aspire. "I paint for immortality" was the reply of an artist who was asked why he lingered so long over one picture. The preacher who sways souls from sin to holiness preaches for eternity. His theme is the cross of Christ, the central point of human history. Scientific men may sneer at such a preacher as narrow because he confines himself to one theme, Christ crucified, not considering that this theme touches all human interests. It gives the amplest scope to mental, moral and spiritual development. The preacher may apply elevating and transforming truth to every state of society and to every subject of human thought. In God's ancient temple the layman could enter no farther than the court of the Jews, but the high priest could enter every apartment. The preacher is God's high priest in the temple of Christian truth to apply truth to all human transactions from the king on the throne to the beggar on the dunghill.
