I think, this 104th Psalm is a fit and proper psalm to preach on in this sweet spring time; for it speaks, from beginning to end, of God's earth, and of His glory, and love, and wisdom which shines forth on this earth. And though, at first sight, it may not seem to have much to do with Christianity, and with the great mystery of our redemption, yet, I believe and know that it has at bottom all and everything to do with it; that this 104th Psalm is as full of comfort and instruction for Christian men as any other Psalm in the whole Bible. I believe that without feeling rightly and healthily about this Psalm, we shall not feel rightly or healthily about any other part of the Bible, either Old or New Testament. At all events God's inspired psalmist was not ashamed to write this psalm. God's Spirit thought it worth while to teach him to write this psalm. God's providence thought it worth while to preserve this psalm for us in His holy Bible, and therefore I think it must be worth while for _us_ to understand this psalm, unless we pretend to be wiser than God. I have no fancy for picking and choosing out of the holy Bible; _all_ Scripture is given by inspiration of God--all Scripture is profitable for doctrine, for reproof, for correction, for instruction in righteousness, and therefore this 104th Psalm is profitable as well as the rest; and especially profitable to be explained in a few sermons as I said before, at _this_ season when, if we have any eyes to see with, or hearts to feel with, we ought to be wondering at and admiring God's glorious earth, and saying, with the old prophet in my text, "Praise the Lord, O my soul. O Lord my God, thou art very great; thou art clothed with honour and majesty. Who coverest thyself with light as with a garment: who stretchest out the heavens as with a curtain: who layeth the beams of his chambers in the waters: who maketh the clouds his chariot: who walketh upon the wings of the wind . . . O Lord, how manifold are thy works! in wisdom hast thou made them all: the earth is full of thy riches" (Ps. civ. 1, 2, 3, 24).
