Then he said to the disciples, "Anyone who accepts your message is also accepting me. And anyone who rejects you is rejecting me. And anyone who rejects me is rejecting God, who sent me."

Luke 10:16

Whatever town or village you enter, search for some worthy person there and stay at his house until you leave. As you enter the home, give it your greeting. If the home is deserving, let your peace rest on it; if it is not, let your peace return to you. If anyone will not welcome you or listen to your words, shake the dust off your feet when you leave that home or town. I tell you the truth, it will be more bearable for Sodom and Gomorrah on the day of judgment than for that town. I am sending you out like sheep among wolves. Therefore be as shrewd as snakes and as innocent as doves.

Matthew 10:11-16
