Some time ago, A Godly Mexican charismatic started laughing at me because I had never heard of a certain popular woman preacher. I looked her up on the internet and found that she lives in a mansion, has servants and expensive cars, and that all of this is being paid for by donors. She was currently being investigated by a Congressional committee for income tax fraud. To make things worse, when I explained this to the Mexican charismatic, she admitted that she knew of Mexicans who lived in concrete houses, whose main food was beans and rice, who were sending this woman money.
2Pe 2:3 ¶ 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.
Preachers who teach "the prosperity Gospel" claim that their wealth (accumulated from donors) is proof of God's blessing. 1 Timothy 6:5 speaks of "men of corrupt minds and destitute of the truth, who suppose that godliness is a means of gain. From such withdraw yourself."
If you want to be used of God, you need to stop following glitzy performers and instead, closely follow after Jesus.
