“Whatever house you enter, stay there and leave from there.” Luke 9:4 HCSB

Later in Luke 10, Jesus offers a better explanation of what is expected of an evangelist who enters a town.

“Whatever house you enter, first say, ‘Peace to this household.’ If a son of peace is there, your peace will rest on him; but if not, it will return to you. Remain in the same house, eating and drinking what they offer, for the worker is worthy of his wages. Don’t be moving from house to house.”

Luke 10:5-7 HCSB

What would be the benefit of having the evangelist stay in one place during his stay in the city? What about the person who wants to see the evangelist, by does not want to come to church. All they would have to do is ask the church and they could say, “He is staying at Judas’ house on straight st.” What a disappointment it would be if that person when to Judas’ house to be told he is at Peter’s house on net st. If anyone wanted to invite the evangelist over could they go there for a meal or fellowship? I think so. but they would have to be back to the hosts' house before too late so that they would spend the night at the same place.  

Would it fall on that house all the extra care needed for the evangelist? To mend the worn-out sandals? To provide the extra shirt if his needed washed? Yes, but it would be a cost God would give back.

“The one who welcomes you welcomes Me, and the one who welcomes Me welcomes Him who sent Me. Anyone who welcomes a prophet because he is a prophet will receive a prophet’s reward. And anyone who welcomes a righteous person because he’s righteous will receive a righteous person’s reward. And whoever gives just a cup of cold water to one of these little ones because he is a disciple — I assure you: He will never lose his reward! ”

Matthew 10:40-42 HCSB

The evangelist would never or stay his welcome as long as he is in tune with God. First, His peace would return back to him when it was time to go. Second, God will move and the evangelist will follow God’s spirit and begin to prepare to leave. 

The English peace is translated from the Greek eirene is along the same line as the Hebrew shalom. Shalom is God’s peace. it is the very peace of God invading our circumstance. It is heaven’s peace overshadowing our earthly chaos. It is peace despite everything that is going on. It was, and probably still is, a customary greeting to say “shalom aleichem” (peace to you) upon entering a house and “aleichem shalom” (to you peace) upon receiving the greeting.

Peace to you all, or maybe less formal Peace y’all.
