What maketh the heart of a Christian heavy? Because he is a pilgrim, and longeth for his country. If thy heart be heavy on this score, although thou hast been prosperous in the world, still thou dost groan: and if all things combine to render thee prosperous, and this world smile upon thee on every side, thou nevertheless groanest, because thou seest that thou art set in a pilgrimage; and feelest that thou hast indeed happiness in the eyes of fools, but not as yet after the promise of Christ: this thou seekest with groans, this thou seekest with longings, and by longing ascendest, and while thou ascendest dost sing the Song of Degrees.
