From a Sermon by Paul Tillich (1886-1965)

You are accepted, accepted by that which is greater than you, and the name of which you do not know.  Do not ask for the name now; perhaps you will find it later.  Do not try to do anything now: perhaps later you will do much.  Do not seek for anything; do not perform anything; do not intend anything.  Simply accept the fact that you are accepted!  If that happens to us, we experience grace.
