From our Basic Training for Church Planting module on Context & Cultivation:

Billy Graham once said that it takes 20 people to lead someone to Christ. The first person thinks they had nothing to do with it. The last person thinks it was all him. The work of cultivation was those first 19 people. And if they’re not careful, they can think their effort was all for nothing.

Smile. Learn to say, “Hello!” Introduce yourself. Be interested in others. Bake cookies for the new neighbors. Get involved in a community organization. If it takes 20, somebody has got to be #1.
