Charles H. Spurgeon on Psalms 104:17

The fir trees. The doors of the temple were made of the fir tree; even of that tree which was a type of the humanity of Jesus Christ. Consider Heb 2:14. The fir tree is also the house of the stork, that unclean bird, even as Christ is a harbour and shelter for sinners. "As for the stork", saith the text, "the fir trees are her house; "and Christ saith to the sinners that see their want of shelter, "Come unto me, and I will give you rest." He is a refuge for the oppressed, a refuge in time of trouble. He is, as the doors of fir of the temple, the inlet of God's house, to God's presence, and to a partaking of his glory. Thus God did of old, by similitudes teach his people his way. John Bunyan, in "Solomon's Temple Spiritualized."
