" We are tempted (and encouraged) to believe that the kingdom of God spreads throughout the earth by presenting the gospel, through some pat formula, to strangers. That doesn't happen very often. The gospel spread throughout the world of the first centuries by conversations between close friends and relatives, business associates and neighbors-people with whom the passionate Christians already had personal contact. So today the Church grows and expands, and people come to maturity in Christ nearly always through the influence of people they already know and trust, like you.

Even the most shy person among us talks to people every day. Most of that talk is idle chatter, not very useful for the advancement of God's kingdom. Every one of those less-than-redemptive conversations is a lost opportunity for extending the Lordship of Jesus. However, if we could learn to enhance the quality of our conversations, we could improve our ability to do what Jesus commanded-make disciples. We could turn that meaningless chatter into a means of God's grace, helping our friends become all God intends for them and enriching their lives (and our own) in the process. "
