When Jesus sent out the seventy, part of His instructions included this,
“But whatever house you enter, first say, ‘Peace to this house.’ And if a son of peace is there, your peace will rest on it; if not, it will return to you” (Luke 10:5-6).
The peace of God was with the seventy, hence it would be with the people in whose homes they stayed, provided that the hosts were people of peace, otherwise, the peace of the evangelists would not abide in that home.
Heaven was with the seventy as they did the work that the Lord authorized them to do.
Likewise, the Lord is with us, and so we bring spiritual blessings to those who are around us.
