The high hills are a refuge for the wild goats, and the rocks for the conies. – Psalm 104:18

I know it is the notion of the bigot, that all the truly godly people belong to the denomination which he adorns. Orthodoxy is my doxy; heterodoxy is anybody else’s doxy who does not agree with me. All the good people go to little Bethel, and nowhere else: they all worship at Zoar, and they sing out of such-and-such a selection, and as for those who cannot say Shibholeth, and lay a pretty good stress on the “h,” but who pronounce it “Sibboleth;”let the fords of the Jordan be taken, and let them be put to death. True, it is not fashionable to roast them alive, but we will condemn their souls to everlasting perdition, which is the next best thing, and may not appear to be quite so uncharitable. Many suppose that because there is grievous error in a church, concerning an ordinance or a doctrine, therefore no living children of God are there. Ah, dear brethren, this severe opinion arises from want of knowing better. A mouse had lived in a box all its life, and one day crawled up to the edge of it and looked round on what it could see. Now the box only stood in a lumber room, but the mouse was surprised at its vastness and exclaimed: “How big the world is!” If some bigots would get out of their box, and only look a little way round them, they would find the realm of grace to be far wider than they dream. It is true that these pastures are a most proper place for sheep, but yet upon yonder hill-tops wild goats are pastured by the Great Shepherd. It is true that yonder plains covered with verdure are best fitted for cattle, but the Lord of all has His beasts in the forest, and His conies among the rocks…You may have to look a long while before you find these living things, but He sees them when you do not, and it is a deal more important to a cony for God to see it, than it is for a man to see it; and so it is an infinitely more weighty matter for a child of God for his Father to know that he is His child, than for his brother to know it. If my brother will not believe me to be a Christian, he cannot help being my brother; he may do what he will in his unkindness, but if I am one of God’s children, and he also is one, the tie of brotherhood cannot be broken between us…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
