They do go beyond what scripture teaches. Theer are thosde who teach things that are borderline heresy and scriptural. There are others who will say they do not know. When I was in seminary one of the professors I had told us that the congregation wants to know. Probably one of the best professors in that convention would often say he did not know when there were times I asked a question. I had more respect and learned more from him than any others.
The congregation may want answers just like all of us but they should not be getting lies from their teachers.
The Lordshipers fail to deal with the reality of church history. They forget about those who denied Jesus and then repented. One of those was Peter. There were many others during times of persecution.
Do we have any examples (like from MacArthur) that take it too far? I have the commentary on James from MacArthur and he makes it clear that it doesn't mean we have to live a perfect life. On page 122 he says, " It will not be perfect obedience and repentance, but good works will be present." Would you consider that taking it too far, or are there other places where he(or others, just using him as an example) has taken it too far.
