One thing about reverend Ike, he told you it was all about money. He didn't try to deceive you. If you got deceived by him you went in wih eyes wide open. :)
I think this passage deals quite nicely with this topic:
2 Peter 1:21-2:3New King James Version (NKJV)
21 for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit.
Destructive Doctrines
2 But there were also false prophets among the people, even as there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Lord who bought them, and bring on themselves swift destruction. 2 And many will follow their destructive ways, because of whom the way of truth will be blasphemed. 3 By covetousness they will exploit you with deceptive words; for a long time their judgment has not been idle, and their destruction does not slumber.
