Luther on Worship

The very highest worship of God is this that we ascribe to him truthfulness, righteousness, and whatever else should be ascribed to one who is trusted. When this is done, the soul consents to his will. Then it hallows his name and allows itself to be treated according to God's good pleasure for, clinging to God's promises, it does not doubt that he who is true, just, and wise will do, dispose, and provide all things well.

--Martin Luther, The Freedom of a Christian
