When the Son of Man comes in his glory, all the nations will be gathered before Him, and He will separate them one from another, as a shepherd divides his sheep from the goats. And He will set the sheep on His right hand, but the goats on the left. Then the King will say to those on His right hand, “Come, you blessed of My Father, inherit the kingdom prepared for you from the foundation of the world: for I was hungry and you gave Me food; I was thirsty and you gave Me drink; I was a stranger and you took Me in; I was naked and you clothed Me; I was sick and you visited Me; I was in prison and you came to Me.’
“Then the righteous will answer Him, saying, “Lord, when did we see You hungry and feed You, or thirsty and give You drink? When did we see You a stranger and take You in, or naked and clothe You? Or when did we see You sick, or in prison, and come to You?’ And the King will answer and say to them, “Assuredly, I say to you, inasmuch as you did it to one of the least of these My brethren, you did it to Me.’

Of what honor, of what blessedness are these words? And He said not, Take, but, Inherit, as one’s own, as your Father’s, as yours, as due to you from the first. For, before you were, says He, these things had been prepared, and made ready for you, forasmuch as I knew you would be such as you are.

And in return for what do they receive such things? For the covering of a roof, for a garment, for bread, for cold water, for visiting, for going into the prison. For indeed in every case it is for what is needed; and sometimes not even for that. For surely, as I have said, the sick and he that is in bonds seeks not for this only, but the one to be loosed, the other to be delivered from his infirmity. But He, being gracious, requires only what is within our power, or rather even less than what is within our power, leaving to us to exert our generosity in doing more.
