In one of the songs I learned in Sunday School there is a finger play that goes along with the words "The church is not a building; the church is not a steeple; the church is not a resting place, the church is the people."
I am thinking of that song as I look at Acts 19
and Paul's stop in the city of Ephesus. The mission of God continues in the synagogue there as well as a lecture hall and in the marketplace. In all these places the Good News about Jesus transforms hearts and lives.
