There are two sources of supernatural power, the power of God, and the counterfeit power of Satan. Whatever God has established, you'll find Satan has counterfeited.
Scripture says that Jesus is the ONLY mediator between God and man and that God alone is to be worshiped:
"For there is one God and ONE mediator between God and men, the man Christ Jesus..."
1 Timothy 2:5
Therefore I will not publish any story of supposed interaction between a person and a "saint," or one who has departed, or with Mary the mother of Jesus.
A second consideration is the "New Age" movement which basically is the world of the psychics, channelers, emergents, and the like. I believe that entire realm to be Satanic.
"There shall not be found among you
anyone who makes his son or his daughter pass through the fire,
or one who practices witchcraft, or a soothsayer, or one who interprets omens,
or a sorcerer, or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead.
For ALL WHO DO THESE THINGS are an abomination to the Lord..."
Deuteronomy 18:10-12
Those are the counterfeits. But they are counterfeits of the real. I believe in healing, miracles, angelic assistance when needed, visions, any and all stories that glorify God in his intervention into the lives of his believers, and would love to hear your story. These are stories that I believe should be published as the Scripture itself has said:
"O give thanks unto the Lord, call upon his name;
make known his deeds among the people.
Sing unto him, sing psalms unto him,
speak of all his wondrous works.
Glory ye in his holy name, let the heart of them rejoice that seek the Lord."
Psalm 105:1-3
