Behold, a certain lawyer stood up and tested him, saying, “Teacher, what shall I do to inherit eternal life?”
He said to him, “What is written in the law? How do you read it?”
He answered, “You shall love the Lord your God with all your heart, with all your soul, with all your strength, with all your mind, (Deuteronomy 6:5); and your neighbour as yourself (Leviticus 19:18).”
He said to him, “You have answered correctly. Do this, and you will live.”
But he, desiring to justify himself, asked Jesus, “Who is my neighbour?”

And then Jesus doesn’t say who his neighbour is.

Jesus instead explained how to be a good neighbour. The implication is that everyone is our neighbour.

How would you feel if the next part of the story detailed a homosexual man who fell afoul of robbers, and a Catholic liberal passed him, then a Baptist Evangelical passed him, but finally was helped on his way by a Muslim?
