This is a typical psalm of praise. Can you figure that out from how many times we hear the phrase: “Praise the Lord”? I would count 12 times that the word “praise” is used in relationship to what we ought to do for God. That is our task and our duty. If you ever memorized the Westminster Catechism, which I never did, you will remember what the first question is: What is the chief end of man? And the answer to that question is: “Man’s chief end is to glorify God, and to enjoy him forever.” I love that answer. What is our chief end, what is the reason for our being? There is no greater reason to live than to glorify Him, read praise Him, and to enjoy him forever. I like that goal.
But if you notice in the psalm it isn’t just the people who are called to praise God. We find that every single living thing is called the praise God. Even the sea monsters! The Leviathan as Psalm 104 and 74 both point to, that creature that God could only have created and loved. Even that sea creature is called to praise the Lord. I wonder if this includes mosquitos.
