It is but a vain thing to talk of going to heaven, if thou let thy heart be encumbered with those things that would hinder. Would you not say that such a man would be in danger of losing, though he run, if he fill his pockets with stones, hang heavy garments on his shoulders, and great lumpish shoes on his feet? So it is here. Thou talkest of going to heaven, and yet fillest thy pockets with stones; that is, fillest thy heart with this world; lettest that hang on thy shoulders with its profits and pleasures. Alas, alas! thou art widely mistaken. If thou intendest to win, thou must strip, thou must lay aside every weight, thou must be temperate in all things. Thou must so run.
– John Bunyan –
