Must Have Bible Support

In the October Christian Chronicle there is a story about a family from Nigeria now living in Atlanta. The article goes:
 
The journey that brought the Ehimares to America began in Benin City, Nigeria. Aburime, then 13, was a street hawker and a devout Pentecostal. He believed that, by speaking in tongues, he could heal the sick---and even raise the dead.
 
When a neighbor's 2-year-old daughter died, the family asked him to do just that. He failed and his faith was shaken. And the story continues.
 
He believed he could do something without support in the Bible.  Sometimes we do the same and when we do we are no different than a 13-year-old street hawker in Benin City, Nigeria who was a devout Pentecostal and thought he could raise the dead.
