May the words of my mouth and the meditation of my heart
be pleasing to you, O LORD, my rock and my redeemer.
— Psalm 19:14 NLT
David prayed earlier in Psalm 19 that the Lord would keep him from sinful deeds of all kinds. In the verse above, he takes the issue deeper by asking that the Lord would also keep him from speaking words that are sinful. From David’s point of view, the things that we say are just as capable of being sinful as the deeds we do and we need the help of the Lord to keep from speaking them just as much as we do to keep from doing sinful deeds.
If our words and meditations are free from sin, then they will be pleasing to the Lord. The word translated as “pleasing” is borrowed from the language of the sacrificial system of the old covenant. The animal sacrifices that were brought before the Lord were required to be without defect, so likewise the words of our mouths and the meditations of our hearts should be without defect. The idea here is that everything we say and think is done before the Lord and should be pleasing to Him as a consequence.
The Lord wants us to be pleasing before Him. He is concerned not only with the deeds we do, but also with the words we say and the thoughts we think.
Today, then, let us ask the Lord to cleanse us, inside and out.
