NCCG's leader, Christopher C. Warren, has made a number of demonstrably false prophecies (see: derekindex.html and prophecyindex.html).

He has been seen to justify these false prophecies through the invention of his own kind of prophecy process called "conceptual revelation". This invented kind of prophecy allows a "prophet" to issue flawed or even effectively "failed" prophecies while excusing the prophet of being labeled a False Prophet.

To accept this invented system as being factual would undermine the most obvious Biblically-indicated tests for determining a False Prophet (Deu 13:1-3, Deu 18:21-22). It appears to be wholly unbiblical, a case of purely invented doctrine. In Warren's case, something like this would have been a necessity for NCCG due to his history of false prophecies.

The original article written by Warren was named "Article 32: The Nature Of Revelation - The Difference Between Conceptual & Verbal-Plenary Revelation".  The section of this article where Warren explains "conceptual prophecy" is shown below, as it was originally visible on the www.nccg.org web site.

.....And though a word of God may fall upon a sinful man briefly and be conveyed in nearly 100% purity by a supreme act of grace on the part of God, this is not usually the case. Rather, He permits those who name His Name to grow in the prophetic office degree by degree so that instead of being "taken over", as it were, by the Spirit and acting as mere channels (pardon the New Age term), they become gradually transformed within (akin to sanctification) so that what they speak is always the word of God.

Without exception, all of us begin as babes in the faith after our first salvation event (born again experience) and grow gradually in knowledge, pure feelings and spiritual sanctification. Though devils may have been cast out of our lives, there is still the old Adam Nature ("flesh", "soulish nature") to deal with. It's there all our lives and but either be subordinated through spiritual discipline, or allowed to control us (partially or wholly). Thus a man or woman growing up in the prophetic gift will experience what we call "muddy revelation", that is, the word of God distorted by the fallen Adam-nature. The diagram below illustrates the concept:

You will see how our false belief (theology, for example) acts as a distorting influence on the pure Spirit of God. Wrong motives, a troubled soul, or simply immaturity, may also add to this distoration, to that the final product, whether written or spoken (or both) is a "muddy revelation". Needless to say such revelation can be very dangerous because it can create in the mind of the one who accepts it a false sense of security in all of it because of the truthfulness of the parts of it that have touched his heart, as the Spirit will indeed do.

As the young prophet matures, his theology becoming more alligned to the Bible as a whole, his thinking and feeling refined and purified, so revelation and prophecy will pass through the human lense increasingly unhindered by the Adam-nature. Time and experience are needed to do this. And thus, with greater prophetic clarity, he may correct any tainted or "muddy" revelations he may have had in the past, as Fig.2 below illustrates:

I know that many Christians are uncomfortable with this kind of "process prophecy", if I may coin this term. It is for this reason that God usually calls His prophets from amongst the older and more mature.

In saying these things we must not confuse this "conceptual revelation" with what is called "verbal plenary revelation". The latter kind, which is rare, implies that every word is literally dictated by God and is therefore 100% perfect. This kind of revelation is only possible if you have a pure language -- and whilst one may obtain 90-95% purity in a modern language like English, for example, you will never get 100% purity.

Deu 13:1  If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder,
Deu 13:2  And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them;
Deu 13:3  Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul.

Deu 18:21  And if thou say in thine heart, How shall we know the word which the LORD hath not spoken?
Deu 18:22  When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that [is] the thing which the LORD hath not spoken, [but] the prophet hath spoken it presumptuously: thou shalt not be afraid of him.

Mat 7:21  Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Mat 7:22  Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
Mat 7:23  And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

Mat 24:24  For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if [it were] possible, they shall deceive the very elect.
