Psalms 19:14

Let the words of my mouth, his sincere prayer, and the meditation of my heart, which dictates the prayer, be acceptable in Thy sight, O Lord, my Strength, the Rock of his refuge, and my Redeemer, by whose deliverance he has been kept time and again. Thus every child of God will pray and sing with mouth and heart, in true faith in the Gospel, in firm trust in the redemption earned by Christ, in whom we have both forgiveness and strength for a life of true sanctification.
