Men are sinners and have no desire to listen to God, yet He graciously continues to speak. The closing prayer of this Psalm is one of the best prayers in the entire Bible. Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer. This prayer should be on our lips and in our hearts throughout each day. The meditation of our heart controls the words of our mouth.
Meditation is to the heart what digestion is to the body.
It is the taking of the Word of God and making it a part of the inner man. As the heart and mind think on the Word of God, the Spirit guides the life. Read this Psalm again and ask God to enable you to love the Word, to live in the Word, and to obey the Word. Psalm 20 is a song of trust. It seems to be a battle hymn, with prayer for victory as David entered battle.
