If a person is what the world calls an honest moral man, if he does justly, and, what the world calls, loves a little mercy, is now and then good-natured, reacheth out his hand to the poor, receives the sacrament once or twice a year, and is outwardly sober and honest; the world looks upon such an one as a Christian indeed, and doubtless we are to judge charitably of every such person. There are many likewise, who go on in a round of duties, a model of performances, that think they shall go to heaven; but if you examine them, though they have a CHRIST in their heads, they have no CHRIST in their hearts.
