God does so much for us. He is the Strength and Promise that undergirds our lives. He is the One who has saved us from sin and death. Our worship comes from our gratitude for what he has done, recognition of who he is, and anticipation of what he is going to do. But worship can never be compartmentalized to just fit into church places or quiet times. Worship involves every aspect of life. That is why it is so important for us to tune the words of our mouths and the motives of our hearts to God's will and work. Then private worship, whether alone in quiet or in a group with Christians, becomes the tuning time for our hearts and lives so that our public worship, our lives lived out in the world, will play the song of God to a world who has not yet heard his tune.
