Evangelism is really not very effective anymore when we attempt to preach AT people. They don't like it, you don't like it, and I don't like being talked to!
Instead, we attempt to know people. Understand their world. Gain their confidence. Walk with them. Maybe over a long period of time they might be interested in knowing more about God, but it takes time and a great deal of time, just to be real, authentic and caring.
