Let My Words Be Acceptable To God.
Let the words of my mouth and the meditation of my heart be acceptable in Your sight, O Lord, my strength and my Redeemer. Psalm 19:14 NKJV
He takes occasion humbly to beg the divine acceptance of those his pious thoughts and affections. Observe the connection of this with what goes before. He prays to God to keep him from sin, and then begs he would accept his performances for, if we favour our sins, we cannot expect God should favour us or our services, Psalm 66:18. Observe, What his services were--the words of his mouth and the meditations of his heart, his holy affections offered up to God. The pious meditations of the heart must not be smothered, but expressed in the words of our mouth, for God's glory and the edification of others and the words of our mouth in prayer and praise must not be formal, but arising from the meditation of the heart, Psalm 45:1.
What was his care concerning these services--that they might be acceptable with God for, if our services be not acceptable to God, what do they avail us? Gracious souls must have all they aim at if they be accepted of God, for that is their bliss.
What encouragement he had to hope for this, because God was his strength and his redeemer. If we seek assistance from God as our strength in our religious duties, we may hope to find acceptance with God in the discharge of our duties for by his strength we have power with him.
In singing this we should get our hearts much affected with the excellency of the word of God and delivered into it, we should be much affected with the evil of sin, the danger we are in of it and the danger we are in by it, and we should fetch in help from heaven against it. - Matthew Henry
