Messages From Heaven About the Future of Our World. Mary, God's Final Preacher, God is always trying to lead man away from self-destruction. He sends his preachers. He sends his teachers. But these are snuffed out. Their words are not listened to and their invitations are rejected. So, finally, he has sent me. I am his final teacher, his final prophet. I am his last opportunity to change the course of history. There is no one behind me, no other message, no other signs than the ones that I will give. When I tell the world that it must listen to me, I am not speaking from a selfish and arrogant spirit. I am speaking as one who sees the destruction, the hopelessness of mankind if my words are not heeded.
