Where the birds make their nests: as for the stork, the fir trees are her house. The high hills are a refuge for the wild goats, and the rocks for the conies. – Psalm 104:17,18

There are to be found God’s people in every city. Some of you are going away, it may be, to the ends of the earth, and this word may be comfortable to you. The Lord has an elect people everywhere. The wild goats are on the rocks, and the conies amongst the stones, and the storks in the trees. Go you where you will, you shall find that God has a living people; or if you should be sent to a country where as yet there are no converted men or women, let not that discourage you, but rather say, “I am sent with the purpose of finding out God’s elect, who as yet are hidden in sin. I am to be the instrument of finding out the Lord’s own blood-bought but hidden ones here.” When thou goest into a city that is given to idolatry, thou shalt hear it said to thee, “I have much people in this city;” go, therefore, and labor to find out the much people. Introduce the gospel, tell of the love of Jesus, and you shall soon find that your efforts are rewarded by the discovery of those who shall love your Savior, and delight in the same truth which now charms your heart. Do not believe that there is a rock without its wild goat; do not think that there is a fir-forest without its stork; or that there are to be found trees by the brook without their birds. Expect to find where God dwells that there are some who are sojourners with Him, as all their fathers were. I love to think that the Lord has His hidden ones even in churches that have sadly degenerated from the faith; and, although it is yours and mine to denounce error unsparingly, and with the iconoclastic hammer to go through the land and break the idols of all the churches in pieces as far as God gives us strength, yet there is not a lamb amongst Christ’s flock that we would disdain to feed; there is not the least of all His people, however mistaken in judgment, whom our soul would not embrace an ardent love. God, in nature, has placed life in singular spots, and so has He put spiritual life into strange out-of-the-way places, and has His own chosen where least we should look for them. ~ C.H. Spurgeon
