May the words of my mouth and the meditation of my heart be pleasing in your sight, O Lord, my Rock and my Redeemer. Psalm 19:14

After singing about many aspects of his walk with the Lord such as the law of the Lord, the precepts of the Lord, the fear of the Lord etc, King David ends his song with a little prayer, "May the words of my mouth and the meditation of my heart be pleasing in your sight..."

Following is an extract from Barnes Notes on the Bible commentary which helps us understand it better:

Let the words of my mouth - The words that I speak; all the words that I speak. And the meditation of my heart - The thoughts of my heart. Be acceptable in thy sight - Be such as thou wilt approve; or, be such as will be pleasing to thee; such as will give thee delight or satisfaction; such as will be agreeable to thee. This supposes:

(a) that God has such control over our thoughts and words, that he can cause us to order them aright;
(b) that it is proper to pray to him to exert such an influence on our minds that our words and thoughts may be right and pure;
(c) that it is one of the sincere desires and wishes of true piety that the thoughts and words may be acceptable or pleasing to God.

Though a simple prayer, it has such deep meaning in it. It would be a great idea to add it to our prayers everyday too; what do you say?
