What could an unsanctified man do in Heaven, if by any chance he got there? Let that question be fairly looked in the face and fairly answered. No man can possibly be happy in a place where he is not in his element and where all around him is not congenial to his tastes, habits and character.
J. C. RyleWhat will it cost [a person] to be a true Christian? It will cost him his self-righteousn ess. He must cast away all pride and high thoughts, and conceit of his own goodness. He must be content to go to heaven as a poor sinner, saved only by free grace, and owing all to the merit and righteousness of another.
J. C. RyleLet us awake to a sense of the perilous state of many professing Christians. 'Without holiness no man shall see the Lord'; without sanctification there is no salvation (Hebrews 12:14). Then what an enormous amount of so-called religion there is which is perfectly useless!
