The mind of Christ is what belongs to the saint as a new man. The Spirit of God first quickened, and now he has the mind of Christ, to mind the things above, as quickened out of the system of this world. He has the intelligence of Christ, through the Holy Ghost and the word. It is the communicated mind of God as it has formed itself in His purposes of Christ.
When taught of God, we shall find proportion, in truth; it will find its place. Where this is not the case, persons will overstate or wrongly apply truth, and find it will not tell. Then, in place of judging themselves, they will judge the truth, and make no progress.
In divine things, error in judgment is connected with wrongness of affection. When the man in the parable said, " I have bought five yoke of oxen, and I go to prove them; I pray thee have me excused," it was as much as to say I prefer oxen to the supper. If a person says, I cannot see, then his eye is not single; he cannot justify himself before God. " If thine eye be single, thy whole body shall be full of light." Whenever we walk in conscience before God, we shall find our path simple; having the mind of Christ, things are as clear as day.
We have in Acts 13. an instance of the ability of applying Scripture, with the mind of Christ, to the circumstances in which they were: " Paul and Barnabas waxed bold and said, it was necessary," etc. In this Scripture we do not find positive particular command to Paul or Barnabas; but, as having the mind of Christ, they could find command there rind say, " for so hath the Lord commanded us..... " The apostle found his place with Jesus. (See Isaiah 49:66And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth. (Isaiah 49:6).)
