“I will praise Thee, O LORD, with my whole heart; I will shew forth all Thy marvellous works.” Psalm 9:1 (KJV)
The Psalmist David will praise the LORD. That is what his heart desires. We know from Biblical history that David was not a sinless man, yet he had a heart for God. He heard God, and when he realized he had sinned he confessed, repented, and received forgiveness.
Whole Heart Praise would be the giving of one’s self to the praise of the one and only who is worthy of praise. True praise is more than words spoken. It is a life lived.
The “Marvellous works” are the works which God is continually doing. Jesus says,
“This is the work of God, that ye believe on Him whom He hath sent.”
We can show for the marvellous works of God through the wonderful works Jesus does in our own lives. Beginning with trusting Him for your eternal salvation.
