In today's Gospel reading from Matthew 25, Jesus made clear to his disciples the following. He will come again in glory as the king to judge all nations and separate the sheep from the goats. The sheep, blessed by the Father, will inherit the kingdom prepared for them from the foundation of the world and the goats, accursed, will depart into the eternal fire prepared for the Devil and his angels. The sheep and the goats are differentiated by whether they gave the king food when he was hungry, gave him drink when he was thirsty, welcomed him when a stranger, clothes him when naked, cared for him when ill, visited him when in prison; and whatever they did (did not do) for one of the least brothers of the king's, they did (did not do) for him.
These most important, astounding messages of Jesus are consistent with all his sayings and revelations. His whole life, his work, completely back him up as a no-nonsense teacher. Again, Jesus becomes an all-or-nothing choice for us. There is no one else who can put us in such a situation without interfering with our free will.
