"But alas, how little fit for heaven are many who talk of 'going to heaven' when they die, while they manifestly have no saving faith, and no real acquaintance with Christ. You give Christ no honor here. You have no communion with Him. You do not love Him. Alas! what could you do in heaven? It would be no place for you. Its joys would be no joys for you. Its happiness would be a happiness into which you could not enter. Its employments would be a weariness and burden to your heart. Oh, repent and change before it be too late!"
J. C. Ryle, "Christ is All," in Holiness: Its Nature, Hindrances, Difficulties, and Roots (1877), cited in John Piper, God is the Gospel (Wheaton: Crossway, 2005), 16.
