Ps 103:17

“"There shall the sparrows build their nests: their leader is the house of the coot" (ver. 17). Where shall the sparrows build? In the cedars of Libanus. ...Who are the sparrows? Sparrows are birds indeed, and fowls of the air, but small fowls are wont to be called sparrows. There are therefore some spiritual ones that build in the cedars of Libanus: that is, there are certain servants of God who hear in the Gospel, "Sell all that thou hast, and give to the poor; and thou shalt have treasure in heaven; and come and follow Me." ...Let him who hath resigned many things, not be proud. We know that Peter was a fisherman: what then could he give up, to follow our Lord? Or his brother Andrew, or John and James the sons of Zebedee, themselves also fishermen; and yet what did they say? "Behold, we have forsaken all, and followed Thee." Our Lord said not to him, Thou hast forgotten thy poverty; what hast thou resigned, that thou shouldest receive the whole world? He, my brethren, who resigned not only what he had, but also what he longed to have, resigned much. ...But although the sparrows will build in the cedars of Libanus, "the house of the coot is their leader." What is the house of the coot? The coot, as we all know, is a water bird, dwelling either among the marshes, or on the sea. It hath rarely or never a home on the shore; but in places in the midst of the waters, and thus usually in rocky islets, surrounded by the waves. We therefore understand that the rock is the fit home of the coot, it never dwelleth more securely than on the rock. On what sort of rock? One placed in the sea. And if it is beaten by the waves, yet it breaketh the waves, is not broken by them: this is the excellency of the rock in the sea. How great waves beat on our Lord Jesus Christ? The Jews dashed against Him; they were broken, He remained whole. And let every one who doth imitate Christ, so dwell in this world, that is, in this sea, where he cannot but feel storms and tempests, that he may yield to no wind, to no wave, but remain whole, while he meets them all. The home of the coot, therefore, is both strong and weak. The coot hath not a home on lofty spots; nothing is more firm and nothing more humble than that home. Sparrows build indeed in cedars, on account of actual need: but they hold that rock as their leader, which is beaten by the waves, and yet not broken; for they imitate the sufferings of Christ.”
