Lord, now lettest Thou Thy servant depart in peace… – Luke 2:29

Saints feel most their readiness to go when their communion with Christ is near and sweet; when Christ hides Himself we are afraid to talk of dying, or of heaven; but, when He only shows Himself through the lattice, and we can see those eyes which are “as the eyes of doves by the rivers of water, washed with milk and fitly set;” when our own soul melteth even at that hazy sight of Him, as through a glass darkly. Oh, then we fain would be at home, and our soul crieth out for the day when her eyes shall see the King in His beauty, in the land that is very far off. Have you never felt the heavenly homesickness? Have you never pined for the home-bringing? Surely, when your heart has been full of the Bridegroom’s beauty, and your soul has been ravished with His dear and ever precious love, you have said: “When shall the day break, and the shadows flee away? Why are His chariots so long in coming?” You have swooned, as it were, with love-sickness for your precious Savior, thirsting to see Him as He is, and to be like Him. The world is black when Christ is fair; it is a poor heap of ashes when He is altogether lovely to us. When a precious Christ is manifested to our spirits, we feel that we could see Jesus and die. Put out these eyes, there is nothing more for them to see when they have seen Him. “Black sun,” said Rutherford, “black moon, black stars, but inconceivably bright and glorious Lord Jesus.” How often did that devout man write words of this sort: “Oh if I had to swim through seven hells to reach Him, if He would but say to me, like Peter, ‘Come unto Me,’ I would go unto Him not only on the sea, but on the boiling floods of hell, if I might but reach Him, and come to Him…Oh, how long is it to the dawning of the marriage day? O sweet Lord Jesus, take wide steps; O my Lord, come over the mountains at one stride!” …When these strong throes, these ardent pangs of insatiable desire come upon a soul that is fully saturated with Christ’s love, through having been made to lean its head upon His bosom, and to receive the kisses of His mouth, then is the time when the soul saith, “Lord, now lettest Thou Thy servant depart in peace.” ~ C.H. Spurgeon
