Each proclamation of the gospel by the minister either leads souls toward life immortal or sends them downward toward a deeper hell. It softens hearts or it hardens them. It brings men upward toward Jesus, or it will justify God in consigning them to the regions of deepest woe. Is it not, then, an awful thing to preach? Who shall attempt to do it until his heart is bathed in the atmosphere and the blood of Calvary?
