Charles H. Spurgeon on Psalms 86:12

I will praise thee, O Lord, &c. Such a soul as David was is enlarged to talk high of God: I will praise thee, O Lord my God, with all my heart; and I will glorify thy name for evermore. Alas! poor creature, how canst thou proclaim him "for evermore"? A soul fired with desire to praise God, burns after both more perfect things and more lasting than it is able to perform. "To will is present with it", etc. See but the reachings and longings of such a soul, how it swells in desires to glorify God! —Thomas Goodwin.
