Restore us to yourself, O LORD, that we may return; renew our days as of old. - Lamentations 5:21
Work that is done with and for God plays its part in God's eternal purposes and so has eternal value; as Jesus put it, it is "treasures in heaven" (Matt. 6:20-21)
We need to find God, and he cannot be found in noise and restlessness. God is the friend of silence. See how nature - trees, flowers, grass- grows in silence; see the stars, the moon and the sun, how they move in silence... We need silence to be able to touch souls.
