Church and mission 11/23-6 to 10 hours of influence

In class yesterday, Professor Bolger said that the average person needs 6 to 10 hours a week with a community in order for them to be influenced by that community. This got me to thinking...How can we as a church influence people for the kingdom of God in this culture? The only regular environment where people spend 6-10 hours together I believe is the workplace. Do we train people adequately to represent Christ in the workplace? What about small groups? That's about 2 hours generally. That's not enough. Sunday morning church service is about 1-2 hours. That's not enough. Any ideas of how to build this 6 to 10 hours of kingdom influence into the week?
