I watch, and am like a sparrow alone upon the house top: I keep a solitary vigil as the lone sentry of my nation; my fellows are too selfish, too careless to care for the beloved land, and so like a bird which sits alone on the housetop, I keep up a sad watch over my country. The Psalmist compared himself to a bird, —a bird when it has lost its mate or its young, or is for some other reason made to mope alone in a solitary place. Probably he did not refer to the cheerful sparrow of our own land, but if he did, the illustration would not be out of place, for the sparrow is happy in company, and if it were alone, the sole one of its species in the neighbourhood, there can be little doubt that it would become very miserable, and sit and pine away. He who has felt himself to be so weak and inconsiderable as to have no more power over his times than a sparrow over a city, has also, when bowed down with despondency concerning the evils of the age, sat himself down in utter wretchedness to lament the ills which he could not heal. Christians of an earnest, watchful kind often find themselves among those who have no sympathy with them; even in the church they look in vain for kindred spirits; then do they persevere in their prayers and labours, but feel themselves to be as lonely as the poor bird which looks from the ridge of the roof, and meets with no friendly greeting from any of its kind.
