If thou wouldst oftener think of thy death than of a long life, no doubt thou wouldst more fervently amend thyself.
And if thou didst seriously consider in thy heart the future punishment of hell or purgatory, I believe thou wouldst willingly endure labor and pain, and fear no kind of austerity.
But because these things reach not the heart, and we still love the things which flatter us, therefore we remain cold and very sluggish.
-- Imitation of Christ
