John 16:12-15
12 I have yet many things to say unto you, but ye cannot bear them now.
13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
14 He shall glorify me: for he shall receive of mine, and shall shew it unto you.
15 All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you. KJV

If we ever start truly believing this and listen nearly every denomination and all cults will fall. Most Megs and Mini churches will close as there will only be a need for one church in each town and city since we will all be in one accord with the Truth. Fleshly and heretical divisions will not exist and the line will be clearly drawn between good and evil as the Truth will do away with gray as gray is an admixture of light and darkness and God has no darkness in Him and neither does His truth.
Sadly, I do not foresee that happening until He returns as we delight as in the days of the Judges to have every man doing that which is right in his own eyes and denying the inconvenient truths that get in the way of our fleshly and prideful desires. Even so, come Lord Jesus and grant us some sort of revival before the end. Amen.
