It is quite obvious that the mind of Christ cannot function by the knowledge of good and evil. A newly born again Christian has a new nature and an old mind. Some changes are made in mind at salvation but the soul-mind goes relatively untouched concerning spiritual matters, by the birthing. The change, or the proper way to say it is; the exchange was made in spirit. The new nature (Christ in you nature) only functions through grace knowledge. So again it becomes quite obvious that the born-again believer needs to know all about our Father's grace. This can only happen through a little word Paul refers to as "revelation." It is by revelation that the believers mind can become compatible with the new "Christ in you" nature. This is where the ministry of the Holy Spirit must take place. He is the only one that can bring revelation and mind renewal to the born-again believer. He is not your Father, He is not your savior and He is not your life, He is your teacher, He is the revealer of the Christ in you. He is Soulish (in your soul) with one primary ministry in mind, that is to teach you the deep things of God, which is "Christ in you the hope of glory." You cannot get any deeper in God than understanding and knowing by revelation that Christ is in you by a birthing, revealed to you, which is spirit taught knowledge (revelation) by the Holy Spirit. As you may have experienced, serving God with your mind only can become a disaster. Not to even speak of being in the dark about the things of God. Another place, Paul uses the word "let" in referring to the mind of Christ, Phil. 2:5, 5 Let this mind be in you, which was also in Christ: Another place, he uses the word "yield" which is a mind function, Romans 6:13, 13 Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God. Paul goes on to use the word "yield" several times in this chapter.
