Yes the renewed mind is the mind of Christ.
In Ephesians 4:22- we are told:
22 That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
23 And be renewed in the spirit of your mind;
24 And that ye put on the new man, which after God is created in righteousness and true holiness.
The "renewed" of verse 23 is the Greek word ananeoō: to renew ... to be renewed in mind, i. e. to be spiritually transformed, to take on a new mind
The renewed mind is not our carnal mind with Bible verses in it ... the renewed mind is the mind of Christ. That is such an amazing truth. And this is something God works within the born again believer (Titus 3:5-6 - Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost Which he shed on us abundantly through Jesus Christ our Saviour)
So ... I'll tell you what I do in my life as far as being transformed by renewing my mind.
every now and again during my day I do what I call a "check up from the neck up". I observe what I am exhibiting in my life in the moment, right then.
If what I see exhibited in my life is the love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance (fruit of the Spirit), then I know I'm good to go ... mind renewed, living in the Lord, abiding in the Vine, etc.
However, if what I see exhibited in my life is the works of the flesh, I know I have been drawn away. Once I realize I have been drawn away, I turn my heart back to the Lord Jesus Christ and go from there. And the Lord is always there when I turn back to Him.
And, yes, sometimes that is moment by moment, depending upon the circumstances I face at any given time in my day.
And I do not believe that is "resurrecting the old man" ... I believe that is recognizing that the treasure which God so lovingly gave to me is held in an earthen vessel.
I do understand you and I understand the importance and significance of living in light of who we are in the Lord Jesus Christ as opposed to who we are in Adam.
I understand 1 John 3:9 (Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God) and I live in light of that truth as best I can.
I also understand that God gives us warning about being drawn away ... about our adversary walking about as a roaring lion seeking whom he may devour ... about be anxious for nothing ...
God would not give us warning if there was no need. And I believe that is all everyone is talking about. We've got some folks on this site who have been walking with the Lord for decades. We've seen and experienced the blessed with all spiritual blessings in Christ Jesus ... as well as the let him that thinketh he standeth take heed lest he fall.
And I think that is all that is being cautioned here. Not that everyone is so focused on the flesh that we do not believe we are able to withstand temptation and overcome the sin issue.
