Since Satan can't destroy the gospel, he has too often neutralized its usefulness by addition, subtraction or substitution.
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. RyleWe must cast away everything which hinders us upon our road towards heaven – the lust of the flesh, the lust of the eye and the pride of life; the love of riches, pleasures and honors, the spirit of lukewarmness and carelessness and indifference about the things of God – all must be rooted out and forsaken if we are anxious for the prize. We must mortify the deeds of the body, we must crucify our affections for this world.
