If the purpose of preaching is illumination—the unveiling of a vision of God’s kingdom—why do we limit that responsibility to only one person in the church? Why not allow others to drop their coins into the box for the encouragement and edification of the whole group? Surely a single mother, or recovering alcoholic, or teenager who has experienced God’s reign can give us a glimpse of the kingdom as well. They, too, have coins to give. Teaching may be the domain of the spiritually mature, but preaching belongs to the whole body.
