Shake The Dust

Jesus tells his disciples that if they enter a home while out on the mission of preaching, and they are rejected, they should leave and shake the dust from their feet.  Someone gave me a good reason for doing this.  By shaking the dust, we are letting go of any grudge we might have against being rejected.  In other words, don't reject someone just because they reject you.  Don't carry the baggage of grudges and resentments with you as you go on your way.  It takes away the ability to be loving when you come to the next encounter.
