The story of the Good Samaritan is not about caring for the sick, but about stopping my busy life for someone I meet who needs my help.
Jesus is asked what the key to eternal life is. The answer is: love of God and love of neighbour. This simple sentence sums up the Old Testament.
But the questioner immediately tries to talk his way out of it by asking who his neighbour is. Jesus responds with a story (Luke 10:25-37).
My neighbour is not a person of my choice. I do not have to seek and fulfil a specific task.
I become a neighbour by changing my behaviour towards the people I meet.
