Also what is the problem with Virgin Mary in this forum? And icons? Is venerating Virgin Mary a sin? Is she a false prophet? Many churches like the Greek Orthodox Church or Catholic Church venerate her. Are they ALL wrong?
Some of us don't believe that she is a mediator. 1Tim 2:5 "For
there is one God, and one mediator between God and men, the man Christ Jesus"
For me, the dead sleep in the grave until the resurrection, so I believe Mary is sleeping until Christ returns.
Aside from that, with a generality, Satan could also predict trends.
Years ago, before I was Christian, I went to a psychic. She told me about the people around me, even down to their horoscope signs, if they were married and had children,or if something had happened to someone recently. However her future prophecies for me never turned out. Satan has angels everywhere who can see who you are close to, etc, and that would lend credibility to things, though he can't predict the future, he can predict likely outcomes.
There is also this in the Bible concerning prophets
Deut 13:1-4 :13 If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder,
2 And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them;
3 Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the Lord your God proveth you, to know whether ye love the Lord your God with all your heart and with all your soul.
4 Ye shall walk after the Lord your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him."
