How Does This Christian Community Spread Throughout The Institution?

Kairos weekends, with their subsequent 2-day retreats, take place every six months once the ministry is launched in an institution. After these small groups have been meeting regularly and participating in the ongoing worship and activities of the institution's chaplaincy program for about 12 months, members of the group suddenly find their peers in the "negative" subculture, in which they have been leaders, coming up to them and saying, "Man, I don't know what it is you've got, but I want it!"...and they then introduce their friend to Christ and the Christian community work of Kairos.
