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

Beloved, saints have drawn their anchor up and spread their sails, when they have been made to hold loose by all there is in this world; and that is generally when they hold fastest by the world to come. To many this world is very sweet, very fair, but God puts bitters into the cup of His children; when their nest is soft, He fills it with thorns to make them long to fly. Alas, that it should be so, but some of God’s servants seem as if they had made up their minds to find a rest beneath the moon. They are moon-struck who hope to do so. All the houses in this plague-stricken land are worm-eaten and let in the rain and wind: my soul longeth to find a rest among the ivory palaces of Thy land, O Immanuel.

Brethren, it often happens that the loss of dear friends, or the treachery of those we trusted, or bodily sickness, or depression of spirit, may help to unloose the holdfasts which enchain us to this life; and then we are enabled to say with David in one of the most precious little Psalms in the whole Book, the 131st, “I have behaved and quieted myself as a child that is weaned of his mother, my soul is even as a weaned child.” I have often thought that if David had said, “my soul is even as a weaning child,” it would have been far more like most of God’s people. But to be weaned, quite weaned from the world, to turn away from her consolations altogether, this it is which makes us cry, “Lord, now lettest Thou Thy servant depart in peace.” Even as the psalmist when he said, “And now, Lord, what wait I for? my hope is in Thee.” ~ C.H.
