My first thought, when I saw this subject line on an email, was of ancient pagans who wanted their coffins, and their crypts, packed full of things to take along into the afterlife.
But then I read this wonderful quote from All In: You are one decision away from a totally different life, by Mark Batterson. And I realized that this had nothing to do with occult visions of an imaginary afterlife; the author simply meant that the man who was his subject was ready at any time to leave for the Christian's ultimate destination.
"A. W. Milne . . . set sail for the New Hebrides in the South Pacific, knowing full well that the headhunters who lived there had martyred every missionary before him. Milne did not fear for his life, because he had already died to himself. His coffin was packed. For thirty-five years, he lived among that tribe and loved them. When he died, tribe members buried him in the middle of their village and inscribed this epitaph on his tombstone:
When he came there was no light.
When he left there was no darkness."
May that be the legacy of every born-again Christian!
