Eternal Praise to an Infinitely Good God

I've been contemplating Psalm 145 this morning.  We've been singing portions of this Psalm during our worship over the last few weeks.  It is a Psalm full of declarations of God's goodness, righteousness, grace and mercy.  Particularly striking, however, are the first three verses.

I will extol you, my God and King,and bless your name forever and ever.  Every day I will bless you and praise your name forever and ever.  Great is the Lord, and greatly to be praised, and his greatness is unsearchable.

According to David there will be no end to the praises given to God.  Because his greatness is unsearchable, because it is beyond man's capacity to fully understand it, the saints in heaven will never exhaust their praises given to God.

Earthly praise for earthly things will always end, because there are limits to earthly goodness.  But God's goodness, the riches of his grace, the wonders of his mercy, the scope of his glory - all of these are infinite and unsearchable by our human minds, and therefore our praises to God simply cannot end.
