I gave this message to a church in San Francisco with whom I have longstanding relationship. I shared with them about how God has scattered through his world six particular categories of clues to attract everyone to himself, and how that effects my own personal ways of sharing Christ with people. The church meets in a rented facility with a drop-dead-line time to exit the building before the next group enters. And since, as usual, I had more to say than time allowed, I moved along pretty quickly through the teaching. So think fast!
