Christians are to see themselves as in exile, but also are to do good to those around them. How do we most effectively serve Jesus in the community? His parable of the good Samaritan provides the way.
And behold, a certain lawyer stood up and made trial of him, saying, “Teacher, what shall I do to inherit eternal life?”
And he said unto him, “What is written in the law? how readest thou?”
And he answering said, “‘Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbor as thyself.'”
And he said unto him, “Thou hast answered right: this do, and thou shalt live.”
But he, desiring to justify himself, said unto Jesus, “And who is my neighbor?”
Jesus made answer and said, “A certain man was going down from Jerusalem to Jericho; and he fell among robbers, who both stripped him and beat him, and departed, leaving him half dead. And by chance a certain priest was going down that way: and when he saw him, he passed by on the other side. And in like manner a Levite also, when he came to the place, and saw him, passed by on the other side. But a certain Samaritan, as he journeyed, came where he was: and when he saw him, he was moved with compassion, and came to him, and bound up his wounds, pouring on them oil and wine; and he set him on his own beast, and brought him to an inn, and took care of him.
And on the morrow he took out two shillings, and gave them to the host, and said, ‘Take care of him; and whatsoever thou spendest more, I, when I come back again, will repay thee.’
Which of these three, thinkest thou, proved neighbor unto him that fell among the robbers?”
And he said, “He that showed mercy on him.”
And Jesus said unto him, “Go, and do thou likewise” (Luke 10:25-37).
