He delivers the attack and then runs for cover knowing that the missile has already been fired. If Brown truly believed his critics were not in danger of the unpardonable sin, why even put it in print in the first place, unless of course you want to deliver the scare in the first place. Imagine Paul, touting apostolic authority, lashing out against them, calling them God Mockers and in danger of blaspheming the Holy Spirit simply because they checked him out with the Holy Scripture. Brown moves on to shame those who will not accept his views. The critics continue to raise their voices and attack those things of which they are ignorant.
Birds fly, fish swim, liars lie, and critics criticize.
Apparently Paul was wrong for commending you for your biblical faithfulness. You are really pathetic ignorant Pharisees. These are only a sampling of Brown's invectives. The truth is the critics are well informed and their reporting is hitting home. He further would have his readers assume that his critics are opposed to revival in general, which simply is not true.
