Seeing Is Believing.
A person had a very close friend in San Fran, they lived in Louisville.
The San Franner appeared to the person in Louisville and said , "I came to say good by, I am dying."
They were dying, they had been stabbed, they were physically still half way across the country.
When this mystical appearance happened the Louisville person was not alone, they were in the company of a friend who did not believe that supernatural things can happen, yet they saw the person from San Fran too, then they became a believer.......
When such things happen to people who are just normally going about their ordinary tasks in life, it really seems to sink it home, invading their mind and compelling their personality to alter some major courses in their own lives.
To suddenly see the unseen world, and know some of the previously unknown shakes us deeply.
