This sermon is just 1 minute 48 seconds long but it sums up the last 35 years of my full time Christian ministry. If I never preached another sermon, this is the one I'd want you to remember me by.
Here's the context - a story Jesus told about being a neighbour.
"On one occasion an expert in the law stood up to test Jesus. “Teacher,” he asked, “what must I do to inherit eternal life?” “What is written in the Law?” he replied. “How do you read it?” He answered, “‘Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind’; and, ‘Love your neighbour as yourself.’” “You have answered correctly,” Jesus replied. “Do this and you will live.”But he wanted to justify himself, so he asked Jesus, “And who is my neighbour?”
In reply Jesus said: “A man was going down from Jerusalem to Jericho, when he fell into the hands of robbers. They stripped him of his clothes, beat him and went away, leaving him half dead. A priest happened to be going down the same road, and when he saw the man, he passed by on the other side. So too, a Levite, when he came to the place and saw him, passed by on the other side. But a Samaritan, as he travelled, came where the man was; and when he saw him, he took pity on him. He went to him and bandaged his wounds, pouring on oil and wine. Then he put the man on his own donkey, brought him to an inn and took care of him. The next day he took out two denarii and gave them to the innkeeper. ‘Look after him,’ he said, ‘and when I return, I will reimburse you for any extra expense you may have.’
“Which of these three do you think was a neighbour to the man who fell into the hands of robbers?” The expert in the law replied, “The one who had mercy on him.” Jesus told him, “Go and do likewise.” (Luke 10:25-37)
“The King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.’" (Matthew 24:40)
