Here is an excellent quote by Mark Dever in an interview with Ed Stetzer about the church:
"The church... is a display of God's own character. We have an invisible God in the Bible. How does He make Himself visible? Is it through icons? We don't have any record of Jesus teaching His disciples to draw or paint or sculpt. He started the church... Our non-Christian friends should see what Jesus is like through the church."
