What's Missing in Today's Church?

It seems that the modern Church has everything! Great organization, great buildings, great orators, great music, great programs, and even great entertainment. But the more "advanced" and "progressive" we become, the more people sense that something is missing. Or "someone" is missing. Where is the Holy Spirit in today's church? Are we embarrassed of Him? Do we put Him in a backroom for those special people who are super spiritual? Can the true Church be the Church without the Holy Spirit and power?
