Psalm 123:2-3

Behold, as the eyes of the servants 

look to the hand of their master,

as the eyes of a maidservant to the hand of her mistress,

so our eyes look to the Lord our God,

till he has mercy upon us.

Israel knew that God is the One who gives mercy. The only rest that satisfies their souls was in God.  They had played the whore with other idols only to experience misery and pain.  It is God who gives mercy, and rest, and peace.  

How desperately we today need to be reminded to come to God for mercy and grace.  We can so easily be tempted to look for hope in other places.  But let us come before God as a servant does his master, as a maidservant does her mistress, and with arms open wide and heads down in worship receive mercy from the one true God.  Mercy and grace flow as naturally from God as water does a fountain.  And He loves to to satisfy His children with Himself.  Let us come before God.
