This problem is all over Latin America as well, we see preacher who ask for money and accumulate wealth going against scripture. This reminds me also the church history with indulgences sales of the middle age that faced Luther and the reformers, we are repiting the history. We can learn from the scripture and our church history how to face this problem. We can try to correct every wrong teaching that is coming out everyday or we can preach the truth and the heresy will disappear.
Great post, totaly agree with you.
