One day a passerby saw a homeless man on the roadside. He stopped for a moment to hand him some loose change and casually said "God bless you, my friend".
"I thank God," said the homeless man, "I am never unhappy."
"What do you mean?" the passerby asked.
"Well," he said, "when the sun is out, I thank God -- when it rains, I thank God. When I am full, I thank God and when I am hungry, I thank God. And, since God's will is my will, and whatever pleases Him pleases me, why should I say I am unhappy when I am not?"
The man looked at him in astonishment and asked, "Who are you?"
"I am a King," said he.
"Where, then, is your Kingdom?" asked the man.
"In my heart." The homeless man replied.
