My heart needs to be tuned daily, hourly even, to sing His praise as it constantly goes out of tune with and toward Him, reaching for the world or being led by my flesh, causing a discordant sound in my soul. But our prayer should be that God will do His work in me, only He can set my heart right. Despite all the things going on in my life, God is still good. God is still constant. And when I sing “Tune my heart to sing thy praise” I am acknowledging to God the condition of my heart.
