"My heart, O God, is steadfast; I will sing and make music with all my soul." (Psalm 108:1)
Psalm 108 combines sections of two earlier psalms, Psalm 57 and Psalm 60, weaving them into a new prayer that moves from personal confidence to communal petition. The opening declares a steadfast heart, the resolute will to praise that does not depend on circumstances: My heart, O God, is steadfast; I will sing and make music with all my soul. The steadfast heart is not the heart that never wavers in feeling but the heart that maintains its direction of will toward God even through changing emotional weather.
The psalm then moves to petition for national deliverance. God's sovereignty over the surrounding nations is declared, and then comes the honest admission: the help of man is worthless. Only with God will they do valiantly. This movement from personal praise to communal petition mirrors the movement of the Lord's Prayer: the personal address, Father, moves to the communal petition for the Kingdom. Individual steadfastness in praise and communal dependence on God are not in tension; they belong together in the life of the Church. The Catechism calls the Church the community of those whose hearts are set on the same Lord and who together cry out for his Kingdom (CCC 2790).
Brothers and sisters, is your heart steadfast toward God today, or is it blown about by the latest emotional weather? The steadfast heart does not claim to be unmoved. It claims to be oriented: whatever I feel, I will sing; with all my soul, whatever the circumstances of the morning. Make that decision before you open anything else today.
Lord God, my heart is steadfast. I will sing and make music with all my soul. With you we will gain the victory. The help of man is worthless, but with God we will do valiantly. Be our God in the morning and our strength through the day. Through Christ our Lord. Amen.
