Psalm 148

Who should offer praise to our God? All of creation. And they do speak out his wonder and glory, but it is not with audible words. Creation praised God through its obedience to his command. Even under his curse creation conforms to his will.
All of the heavenly hosts should speak God's praise. Scripture indicates that there is a vast majority of the angels still bow before the majestic throne in worship.
Finally all of mankind should offer God praise, but like the heavenly host far too many have rejected God and are in rebellion against his commands.  We should strive to keep a submissive attitude toward Jesus.
It took me about 3 minutes to read this psalm.
