"Usefulness is nine-tenths availability. When others need help, they don't need it two days from now." Richard A. Swenson, M.D., Margin
"We must be ready to allow ourselves to be interrupted by God. God will be constantly crossing our paths and canceling our plans by sending us people with claims and petitions... It is part of the discipline of humility that we must not spare our hand where it can perform a service and that we do not assume that our schedule is our own to manage, but allow it o be arranged by God."
Deitrich Bonhoeffer - Life Together, page 99
