Read the text: Psalms 138
The ground of faith — God's word
Psalm 138 gives the ground of faith — God's word; and now the godly turns to own it in worship; and when that word reaches the kings of the earth, they shall turn and praise Jehovah and sing in His ways. Nor is His truth all. Though so high, He has respect to the lowly; He revives, protects, and perfects all that concerns the believing righteous. "His mercy endures for ever."
