Small, but mighty. Short and sweet. How to say a lot in a few words. “If you want to know how to praise God, then here is the answer. Summon people to do so, and then give the reasons.” John Goldingay. Psalm 117 is the tiniest of all psalms yet reaches to the farthest corners of the earth and invites every single person to join the ever-widening circle and sing praise to God.
