We can certainly leave the judging of peoples' ministries to God. But that is not the same as proving all things and holding fast to that which is good.Since then, I leave another's ministry alone lest I trample God's work...
WOF false teachings are not limited to just the name it and claim it aspect. They have many other false doctrines which they blatantly preach and mislead people. Simply promoting the idea that tithing will bring material rewards is ABSOLUTE NONSENSE. There is nothing in the New Testament to support this. But there are other false teachings which are very harmful also.
