“We are all naturally self-righteous. It is the family disease of all the children of Adam.”
J. C. Ryle
What 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.
