The prayer of David is that not only his spoken words would be acceptable to the Lord, but also the meditation of his heart. He has spent the previous verses of Psalm 19 declaring God’s clarity when he speaks, even when he doesn’t use words. In the same way, David asks that he not be double-minded, speaking one thing with his lips, but another in his heart. This is, however, a truth about our sinful selves.
Knowing this, David declares his faith in the Lord who is his rock and redeemer. Because we are all bent toward duplicity, we need one to come and save us, and establish us on a sure foundation.
Being a Christian means speaking truth. A church once hung a banner outside of its front door reading, “Truth Told Here!” Knowing God allows us to know the truth and the ability to speak it. By this I mean that we are able to be honest about who we are, but moreover, honest about who God is and what he has done for us in Jesus.
Let the words of my mouth and the meditation of my heart be acceptable in your sight, O Lord, my rock and my redeemer. (Psalm 19:14)
O Lord, make us speakers of your truth. May all that we say and do bring honor to your name, but also the thoughts and desires of our hearts. We ask this in the name of Jesus, who is our rock and redeemer. Amen.
