Psalms 144-150: Let Everything That Has Breath

The Psalmist was right when he said:
O LORD, what is man that you care for him,
the son of man that you think of him?
Man is like a breath;
his days are like a fleeting shadow. - Ps.144:3-4 NIV

Your kingdom is an everlasting kingdom,
and your dominion endures through all generations. - Ps. 145:13 NIV
 
Do not put your trust in princes, in mortal men, who cannot save.
When their spirit departs, they return to the ground;
on that very day their plans come to nothing.
Blessed is he whose help is the God of Jacob,
whose hope is in the LORD his God, the Maker of heaven and earth,
the sea, and everything in them—the LORD, who remains faithful forever. - Ps.146:3-5 NIV

Considering all of this,  who God is and how limited we are in scope to his power and majesty, it is fitting that the Psalms end as they do with the 150th Psalm.  This great and awesome God, the Maker of heaven and earth, whose kingdom endures forever, has from the beginning of time, and will until the end continue to care for his creation.  What have we done to deserve it?  What can we do other than:

Praise the LORD.
Praise God in his sanctuary;
praise him in his mighty heavens.
Praise him for his acts of power;
praise him for his surpassing greatness.
Praise him with the sounding of the trumpet,
praise him with the harp and lyre,
praise him with tambourine and dancing,
praise him with the strings and flute,
praise him with the clash of cymbals,
praise him with resounding cymbals.
Let everything that has breath praise the LORD.
Praise the LORD. - Ps. 150 NIV
