As we reach out and serve, the impact of authentic love is so counter to the normal experiences of most people that they are intrigued. So they may open the door with a question. On the other hand, it may be that people appreciate our kindness, but never ask why we do what we do. They may just assume that we're "nice." So at some point, God asks us to be bold, and to initiate the conversation. This can be a bit scary. But remember, we don't need to have answers to all of the hard theological questions. We just need to be ready to share our own experiences, and to state clearly and simply how Jesus has changed our lives.
