Neither should the spiritual believer be apathetic. It has pride and ill-will in the mix, is distructive to those who seek to serve God wholeheartedly, or those who follow these kinds of quality of leaders in the forefront of a revival in the making.
These divisive individuals must be exposed. - but one better KNOW who they are IN CHRIST in so doing. Do not think your self qualified in God's Sight for such an exposure of these fruitless deeds, unless you know who you are IN CHRIST, and know whose you are with His backing to do so. "Do not think yourself more highly than you ought (Rom. 12:3)."
Let these divisive ones dig themselvels deeper deeper into a pit they have dug for themselves.
