Your statement "the false christ that glows with glory and heals the sick" is impossible according to Jesus in the gospel of Mark 3, 22-29.
22 And the scribes which came down from Jerusalem said, He hath Beelzebub, and by the prince of the devils casteth he out devils.
23 And he called them unto him, and said unto them in parables, How can Satan cast out Satan?
24 And if a kingdom be divided against itself, that kingdom cannot stand.
25 And if a house be divided against itself, that house cannot stand.
26 And if Satan rise up against himself, and be divided, he cannot stand, but hath an end.
27 No man can enter into a strong man's house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house.
28 Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme: 29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation.
What Jesus is saying here is that the devil (as you say) cannot turn against himself. He cannot throw himself out; that is, throw out evil spirits, disease, sickness, etc—HE CAN'T HEAL THE SICK BECAUSE HE IS THAT VERY THING! And in 29 Jesus is very clear that with the Holy Ghost you can, and those who don't believe and speak against it are "in danger of eternal damnation".
Believe it! God is all powerful!
