The Making of a Minister – Paul M. Williams

1 Samuel 22:1-3 "The world's greatest men usually enter incognito. The tough youngsters who gathered in Jesse's back yard of a summer afternoon to play the ancient equivalent of piggy-move-up would not have shoved Jesse's youngest boy around quite so freely if they had had a touch of second sight to let them see that they were taking liberties with the greatest king Israel was ever to know.  But their blindness made possible many a glorious day of fun for the boys in the neighborhood...Such are the ways of God when He prepares His saints and heroes:  He leaves them unrecognized by the world until the day of their "showing unto Israel"". – A.W Tozer
