Verse 12. I will praise thee, O Lord my God, with all my heart. When my heart is one, I will give thee all of it. Praise should never be rendered with less than all our heart, and soul, and strength, or it will be both unreal and unacceptable. This is the second time in the psalm that David calls the Lord "my God", the first time he was in an agony of prayer ( Psalms 86:2 ), and now he is in an ecstacy of praise. If anything can make a man pray and praise, it is the knowledge into that the Lord is his God.
And I will glorify thy name for evermore, eternity gratitude will prolong its praise. God has never done blessing us, let us never have done blessing him. As he ever gives us grace, let us ever render to him the glory of it.
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 12. I will praise thee, O Lord my God, with all my heart: and I will glorify thy name. We glorify God by praising him. Doxology, or praise, is a God exalting work. Psalms 50:23 . "Whoso offereth praise glorifieth me." The Hebrew word, Bara, to create, and Barak, to praise, are little different, because the end of creation is to praise God. Though nothing can add to God's essential glory, yet praise exalts him in the eyes of others. When we praise God, we spread his fame and renown, we display the trophies of his excellency. In this manner the angels glorify him; they are the choristers of heaven, and do trumpet forth his praise. Praising God is one of the highest and purest acts of religion. In prayer we act like men; in praise we act like angels. Believers are called "temples of God", 1 Corinthians 3:16 . When our tongues praise, then the organs of God's spiritual temple are sounding. How sad it is that God hath no more glory from us in this way! Many are full of murmuring and discontent, but seldom bring glory to God, by giving him the praise due to his name. We read of the saints having harps in their hands, the emblems of praise. Many have tears in their eyes and complaints in their mouths, but few have harps in their hands, blessing and glorifying God. Let us honour God this way. Praise is the quit rent we pay to God: while God renews our lease, we must renew our rent. -- Thomas Watson.
Verse 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.
Verse 12. With all my heart. When my heart is united to fear thy name, then shall I praise thee with my whole heart. --Adam Clarke.
