plainly and directly, are those, who with the name indeed of Christians, have hitherto passed their lives without any internal religion whatever; who have not at all thought upon the subject; who, a few easy and customary forms excepted (and which with them are mere forms), cannot truly say of themselves, that they have done one action, which they would not have done equally, if there had been no such thing as a God in the world; or that they have ever sacrificed any passion, any present enjoyment, or even any inclination of their minds to the restraints and prohibitions of religion; with whom, indeed, religious motives have not weighed a feather in the scale against interest or pleasure. To these it is utterly necessary that we preach conversion.” {51a} “The next description of persons to whom we must preach conversion, properly so called, are those who allow themselves in the course and habit of some particular sin, with more or less regularity in other articles of behaviour; there is some particular sin, which they practise constantly and habitually, and allow themselves in that practice. Other sins they strive against, but in this they allow themselves. Now no man can go on in this course consistently with the hope of salvation; therefore, it must be broken off. The essential and precise difference between a child of God and another is, that the true child of God _allows himself_ in no sin whatever; cost what it may, he contends against, he combats all sin; which he certainly cannot be said to do, who is still in the course and habit of some particular sin; for as to that sin, he reserves it, he compromises it. Here then we must preach conversion.” {51b} “In these two cases, therefore, men must be converted and live, or remain unconverted and die.” {51c}
