Psalm 103

Not lip service.  Not the perfunctory prayer before a meal.  Not ritualistic prayer on the Lord's Day. Not the repeated bedtime prayer.

No....In response to meditating on God's greatness in all things, particularly His mercy, the psalmist is moved to direct his whole being to praise Him......heart, mind, soul, body.  When we understand fully (or as fully as we can) God's character and scope, it should indeed throw us into a 'whole being' sort of worship.  Especially when we get a glimpse of His great mercy toward us.

"Remember!" cries the psalmist.......remember His benefits to you!
     He forgives.
     He heals.
     His lovingkindness and mercy are upon you.
     He provides for and sustains you.

His righteousness and justice are expressed toward us.  He is slow to anger (we deserve His immediate wrath!), abounding in mercy, and does not deal with us as we deserve.

I am drawn to Lamentations 3:22-25.  Jeremiah is remembering the bitter discipline of the Lord, and rather than be depressed about it, he is encouraged.......He remembers, and states he has hope.
    "Through the Lord's mercies we are not consumed, because His compassions fail not.  They are new every morning; Great is Your faithfulness.  'The Lord is my portion,' says my soul, therefore I hope in Him!"

See also Ps. 78:38,      Neh. 9:17,31,       Micah 7:18-19

His mercy is as great as His creation, and He removes our sin from us as far as the ends of that creation.  His pity for us is like that of an earthly father-----because He understands 'our frame'....that we are finite and broken.  Though our lives are but a moment in light of His infinite nature, e remembers us, and keeps His covenant with those who fear Him and do His commandments.

His throne is established and cannot be shaken.  His rule is over all.

In light of these things.....Bless the Lord!  With your whole being!
