Involved in the GREAT COMMISSION
After his resurrection, Jesus appeared to His disciples and gave The Great Commission: "All power is given unto me in heaven and in earth. Go ye, therefore, and disciple all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost. Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the age."
The Great Commission isn't about "saving souls." It's about Jesus, his authority and pushing His presence into every square inch of His creation. Jesus' authority isn't over some spiritual realm or "my heart," but it is over all things, in heaven and in earth. This authority extends to every subject (biology, economics, physics) and "ology" at the university. These earthly things are part of the Great Commission. We believe public preaching is part of fulfilling the Great Commission.
