Changed (P2)

How do we obey the command in Romans 12:2 to “be transformed in the renewing of your mind?”

First, before we can do anything, an action of the Holy Spirit is required and then we join him in these actions. The reason the Holy Spirit is required is because this word “renewal” in Romans 12:2 is only used one other place in all of the Greek Bible, namely, Titus 3:5 where Paul says this: “[God] saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit.”

There’s the word “renewal” which is so necessary and it is renewal “of the Holy Spirit.” The Spirit renews the mind. It is first and decisively his work. We are radically dependent on him. Our efforts follow his initiatives. 
Now what is the work that he must do to renew our minds so that all of life becomes worship?

2 Corinthians 3:18 sets the stage for the answer:

"And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit." 

What does the Spirit do to “transform” us into the image of the Son of God? He enables us to “behold the glory of the Lord.” This is how the mind is renewed by steadfastly gazing at the glories of Christ for what they really are.

But to enable us to do that, the Spirit must do a double work. He must work from the outside in and from the inside out. He must work from the outside in by exposing the mind to Christ-exalting truth. That is, he must lead us to hear the gospel, to read the Bible, to study Christ-exalting writings of great, spiritual men, and to meditate on the perfections of Christ.

This is exactly what our great enemy does not want us to do according to 2 Corinthians 4:4:

“The god of this world [Satan] has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ.”

Because to see that for what it really is, Paul says, will renew the mind and transform the life and produce unending worship.

And the Spirit must work from the inside out, breaking the hard heart that blinds and corrupts the mind. The Spirit must work from the outside in, through Christ-exalting truth, and from the inside out, through truth-embracing humility. If he only worked from the outside in, by presenting Christ-exalting truth to our minds but not breaking the hard heart and making it humble, then the truth would be despised and rejected. And if he only humbled the hard heart, but put no Christ-exalting truth before the mind, there would be no Christ to embrace and no worship would happen.
