I don't hear many arguments concerning "if" we should do evangelism. I'm willing to bet you a corndog that there are events on your church calendar right now that are designed to be evangelistic. But, are they destined to be draw events?
A harvest event must be proceeded by seeds. One of the greatest seeds is love. Events destined to be successful are ones proceeded by planting love. We must show and shine love before or as we share love. Designed evangelistic events are destined to be successful when love is planted.
