Heaven and Hell
They entered a room identical to the first, the big pot of stew, the group of people and the same long-handled spoons. But here everyone was happy and well nourished. "I don't understand" said the man. "Why is everyone happy here and miserable in the other room? Everything is the same."
"Here, said the Lord, they have learned to SERVE each other."
Addendum -- Galatians 5:13-14 (NKJ) "For you brethren, have been called to liberty; only do not use liberty as an opportunity for the flesh, but through love SERVE one another. For all the law is fulfilled in one word, even in this: 'You shall love your neighbor as yourself.'"
