Then the King will say to those on the right, 'Come, you who are blessed by my Father, inherit the Kingdom prepared for you from the foundation of the world.
For I was hungry, and you fed me. I was thirsty, and you gave me a drink. I was a stranger, and you invited me into your home.
I was naked, and you gave me clothing. I was sick, and you cared for me. I was in prison, and you visited me.'
"Then these righteous ones will reply, 'Lord, when did we ever see you hungry and feed you? Or thirsty and give you something to drink?
Or a stranger and show you hospitality? Or naked and give you clothing?
When did we ever see you sick or in prison, and visit you?'
And the King will tell them, 'I assure you, when you did it to one of the least of these my brothers and sisters, you were doing it to me!'
