“Which now of these three, thinkest thou, was neighbour unto him that fell among the thieves? And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise.” - Luke 10:36, 37.
That we are neighbours to one another is the moral lesson which Jesus Christ our Lord and Savior taught us in what is now popularly known as the parable of the Good Samaritan. A lawyer had asked Jesus Christ “who is my neighbour?” (Luke 10:29) Jesus Christ did not answer the question directly but related the story of a certain man who was going down from Jerusalem to Jericho, and was attacked by robbers who wounded him and left him half dead. A priest saw him but passed another way. A Levite passed also, saw him and passed by. It was a Samaritan, that helped him. (Luke 10:33-35).
From the parable it was clear who was neighbour to the injured man. It was then Jesus Christ charged the lawyer, “Go, and do thou likewise”. Christians too should be busy doing likewise. Apostle John stated, “But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him? My little children, let us not love in word, neither in tongue; but in deed and in truth.” - 1 John 3:17, 18.
