At the end of Psalm 72, David blesses God. Notice 4 things about the praise he gave which instruct us:
— “Blessed be the LORD God, the God of Israel.”
Praise is due to this specific God: YHWH, of Israel — the God of the Bible, of the Messiah, not Baal or Asherah or any other of the gods of the nations. Only this God is worthy of praise. David knew nothing of the “generic” god that so many refer to today. He referred to Yahweh, who revealed Himself to Moses in Exodus 3, the God who enabled him to defeat Goliath, the God who inspired the scriptures, the God who promised the Messiah — THIS specific God is the God David called us to praise!
— “Who alone works wonders”
The God David referred to is the exclusive God. No one else “works wonders”; no one else does what He can do; He is the ONLY God to be praised. As the First Commandment says, “You shall have no other gods before Me”!
— “And blessed be His glorious name forever”
The praise which is given to this God alone will never stop being given. His name will be praised “forever.” Revelation 4:8 tells us that the created beings in heaven “never cease to say, ‘Holy, holy, holy is the Lord God almighty” — and one day His people will join that everlasting song!
— “And may the whole earth be filled with His glory”
Just as His presence is everywhere, and His sovereign power rules everywhere, so His name is to be praised everywhere. “The whole earth” is to be filled with His glory and praise.
As the people of God, this is to be our primary business: to praise God — not just any God, but the God of the Bible, the God and Father of The Lord Jesus Christ, and Him alone. And our praise for Him is to be everywhere, and forever — just as David modeled for us here!
