The final 5 psalms form a 5 part Hallelujah by beginning and ending with that very word: “Praise the Lord! One part for each book of the Psalter. 

Psalm 146 reminds us that our life is precarious. And it is a praise to God. With that limited view of life in mind, where do we find hope to praise God forever? 

Our help cannot be found with the powerful or any force on this earth. Only with the LORD who has made heaven and earth and who cares for those who are low. This psalm even makes clear the work of Jesus in Matthew 11 clear. 

Indeed, blessed is the one who has the LORD as his helper. The final time in the Psalms that we hear the word Blessed.
