What would they judge of thee if they knew thy heart began to fail thee in thy journey, or thy sins began to allure thee, and to persuade thee to stop thy race? would they not call thee a thousand fools? and say, O, that he did but see what we see, feel what we feel, and taste of the dainties that we taste of! O, if he were here one quarter of an hour, to behold, to see, to feel, to taste and enjoy but the thousandth part of what we enjoy, what would he do? What would he suffer? What would he leave undone? Would he favour sin? Would he love this world below? Would he be afraid of friends, or shrink at the most fearful threatenings that the greatest tyrants could invent to give him? Nay, those who have had but a sight of these things by faith, when they have been as far off from them as heaven from earth, yet they have been able to say with a comfortable and merry heart, as the bird that sings in the spring, that this and more shall not keep them from running to heaven.
—John Bunyan, The Heavenly Footman
