Servant evangelism involves intentionally sharing one's faith through acts of service without any strings attached. It can be an effective way to reach people in today's culture and allows laypeople to creatively initiate ministry opportunities. Some examples provided include washing cars or windows, handing out snacks or other gifts, and serving the community through projects like car washes. The document emphasizes that people come to know Christ gradually through multiple exposures, so servant evangelism is meant to build bridges over time rather than expecting immediate conversions.
