Hospitality
And again [the Scripture] saith, “God brought forth Abram, and spake unto him, Look up now to heaven, and count the stars if thou be able to number them; so shall thy seed be. And Abram believed God, and it was counted to him for righteousness.” On account of his faith and hospitality, a son was given him in his old age; and in the exercise of obedience, he offered him as a sacrifice to God on one of the mountains which He showed him.
At the end of the discourse (vv. 40–42) it will be made clear that how people respond to them reveals also their response to Jesus the Messiah. That is why the welcome or lack of it which they will encounter in the villages of Galilee is so strongly emphasized in vv. 11–15; the villagers will be welcoming or rejecting their Messiah. The “peace” which will rest on the “worthy” is not just a social formality, but a real mark of God’s blessing or judgment. This is a moment of spiritual decision, however little some of the people of Galilee may yet recognize it as such.
