Quoted in Sojourners:
What God requires of those who call on God's name is responsive servanthood. God wishes to act in and through us, so Christian hope does not relieve men and women of responsibility. We are not primarily responsible for shrewd analysis of problems, for strategic selection of means, for maximizing the chances of success. We are primarily responsible for turning to God, for attempting to know and do God's will. That well may lead us into actions which are not shrewd, strategic, or successful, as the life of Jesus suggests. But as Jesus' life demonstrates, human action which is faithful to God's will can have transforming effect.
--- Parker Palmer from "The Company of Strangers"
When you get to your wit's end, you'll find God lives there.
