The Born again believer at spiritual birth is basically left with the knowledge Adam and Eve recieved in the garden. "The knowledge of good and evil," that knowledge, as mentioned before is a mind controller and does not relinquish it's ways easily. Hence the born again believer is admonished to get his/her mind renewed. For the born-again believer the mind functions either by the knowledge of good and evil or it functions by grace (revelation) knowledge from the HolySpirit. The importance of "Christ in you" knowledge cannot be expressed enough at this point. It takes this mind to be compatible with the "Christ in you" life-nature. This is what Paul calls "the mind of Christ." When the mind receives revelation it becomes compatible with your new nature. Revelation cannot be controlled, one of the main reasons Paul uses the word "yield" is because at this point you have to "allow" the Holy Spirit to teach you Christ. I have been asked many times about the teaching of man, at this point no man can teach you Christ, only the HolySpirit can teach you Christ. Grace knowledge eliminates any need for control. Have you ever noticed if you start to get a little revelation religion will rear its ugly head to try to stop it, because revelation cannot be controlled. Religion will stop anything it cannot control. Most believers at first are prone to reject revelation because it is not a mind controllable knowledge. Paul calls revelation, the hidden wisdom of God, 1 Cor. 2:6-7, 6 Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world, that come to nought: 7 But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory: This wisdom (revelation) has been ordained by God before the foundation of the world, for you.
