What does Psalm 47:6 mean?

Four times in this psalm the writer calls upon his audience to worship and celebrate the Lord with songs. The first time he solicits praise to God (Psalm 47:1). The next three times, two of which are in this verse, he calls for praise to God as our King (Psalm 47:7). Some commentators connect this to a real-world victory, such as those over Sennacherib (2 Kings 19:35–37) or during the rule of Jehoshaphat (2 Chronicles 20:22–26). Others see it as general praise, or as part of a prophetic celebration of the Messiah's rule over the entire earth.

God's role as King extends to all aspects of creation. He commands myriad angels. He created all things. He merely spoke and everything came into existence (Genesis 1:1; Hebrews 11:3). The same God knows the sparrow's fall and has promised to meet every need His people have. He is omnipotent. omniscient, omnipresent, and immutable. He never changes (Malachi 3:6). His faithfulness, love, mercy, and grace continue unchanged forever. He deserves to be praised forever. As King, He has the right to rule the world and everything in it, including human beings. His kingdom is universal, and someday it will be an earthly kingdom ruled by the Messiah. It will be marked by peace, justice, and righteousness (Isaiah 9:7). All praise is due His holy name!
