The Person of Peace is often mis-defined as someone who is open to talking about Jesus (spiritually open).
That's where a Person of Peace begins, but not where the definition ends (at least, our definition).
A Person of Peace is:
1) open to the message of Jesus
2) receptive to the messenger (will invite him/her into their circle of friends/family) ("Can I come to your home" is an important filter. Are they welcoming the Gospel in, or are they just willing to tolerate me in the street?)
3) influential in their social network, and bringing others to the message.
These three factors converging in a single individual can be a catalytic hub for the Gospel.
