The King will answer and say to them, 'Truly I say to you, to the extent that you did it to one of these brothers of Mine, even the least of them, you did it to Me.'
Then He will also say to those on His left, 'Depart from Me, accursed ones, into the eternal fire which has been prepared for the devil and his angels; for I was hungry, and you gave Me nothing to eat; I was thirsty, and you gave Me nothing to drink; I was a stranger, and you did not invite Me in; naked, and you did not clothe Me; sick, and in prison, and you did not visit Me.'
Then they themselves also will answer, 'Lord, when did we see You hungry, or thirsty, or a stranger, or naked, or sick, or in prison, and did not take care of You?'
Then He will answer them, 'Truly I say to you, to the extent that you did not do it to one of the least of these, you did not do it to Me.'
These will go away into eternal punishment, but the righteous into eternal life."
One of the points that jump out at me from this parable that Jesus tells is that the Sheep were serving God without even knowing it. They were going about their lives, taking care of those in need completely unaware that they were serving God. They were shocked and surprise that they had been loving God himself when they were loving the less fortunate.
The goats were caught off guard by what they heard. They had no idea that they had neglected God himself by not taking care of those in need around them.
Beethoven and Paul most likely did not know that their work would not only stand the test of time but touch many generations after their deaths. The sheep in the story also did not know that their lives were of great significance and that the simple things that they did would have eternal consequences. Our actions can and do have an impact far past our ability to comprehend what we are doing.
