Verse 5. Be thou exalted, O God, above the heavens: and thy glory above all the earth. Let thy praise be according to the greatness of thy mercy. Ah, if we were to measure our devotion thus, with what ardour should we sing! The whole earth with its overhanging dome would seem too scant an orchestra, and all the faculties of all mankind too little for the hallelujah. Angels would be called in to aid us, and surely they would come. They will come in that day when the whole earth shall be filled with the praises of Jehovah. We long for the time when God shall be universally worshipped, and his glory in the gospel shall be everywhere made known. This is a truly missionary prayer. David had none of the exclusiveness of the modern Jew, or the narrow heartedness of some nominal Christians. For God's sake, that his glory might be everywhere revealed, he longed to see heaven and earth full of the divine praise. Amen, so let it be.
Now prayer follows upon praise, and derives strength of faith and holy boldness therefrom. It is frequently best to begin worship with a hymn, and then to bring forth our vials full of odours after the harps have commenced their sweeter sounds.
