Preaching In A Visual Age

Does the fact that our generation is so video oriented call for the church to change the way we evangelize the lost and teach the saints? Does God ordain the method of evangelism as well as the message? Are we free to accept culturally relavant methods of communication to accomplish the work of the church? What did Paul say in I Corinthians 1:17-2:5? Today's church runs the risk of emptying the gospel of its power via cultural accomodation.
