I saw on a Facebook post where a "Pastor" says that if a person pays millions to a witch doctor for a protection charm and later wants a man of God to break the curse, he or she needs to pay an amount greater than what was paid before the charm was planted. If not the charm will swallow him and his family. I want to know if this is correct and with scriptural backing so that I can exhort this friend of mine.
Witchcraft, in all forms, is fake. See: Is Witchcraft Real? Thus, the person paying money to a witchdoctor has paid money for nothing and there is nothing to be removed.
The so-called pastor is trying to use people's ignorance of God's teachings to personally make money. "If anyone advocates a different doctrine and does not agree with sound words, those of our Lord Jesus Christ, and with the doctrine conforming to godliness, he is conceited and understands nothing; but he has a morbid interest in controversial questions and disputes about words, out of which arise envy, strife, abusive language, evil suspicions, and constant friction between men of depraved mind and deprived of the truth, who suppose that godliness is a means of gain" (I Timothy 6:3-5). Even if there were a true curse (which there is not) God is not looking for money to free people from the effects of sin. "But Peter said to him, 'May your silver perish with you, because you thought you could obtain the gift of God with money!'" (Acts 8:20).
