Ok, so: here is the textbase of texts (now in the RSV) from Paul’s letters. I think this is every passage where he speaks of discipleship in terms of our minds/hearts/thoughts.
The first group is passages that set the pattern I think I see:
Romans 6.8-11 But if we have died with Christ, we believe that we shall also live with him. For we know that Christ being raised from the dead will never die again; death no longer has dominion over him. The death he died he died to sin, once for all, but the life he lives he lives to God. So you also must consider yourselves dead to sin and alive to God in Christ Jesus.
Romans 8.5-8 For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit. To set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. For the mind that is set on the flesh is hostile to God; it does not submit to God’s law, indeed it cannot; and those who are in the flesh cannot please God.
Romans 12.1-3 I appeal to you therefore, brethren, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world but be transformed by the renewal of your mind, that you may prove what is the will of God, what is good and acceptable and perfect. For by the grace given to me I bid every one among you not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith which God has assigned him.
Ephesians 4.22-24 Put off your old nature which belongs to your former manner of life and is corrupt through deceitful lusts, and be renewed in the spirit of your minds, and put on the new nature, created after the likeness of God in true righteousness and holiness.
Philippians 4.6-8 Have no anxiety about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which passes all understanding, will keep your hearts and your minds in Christ Jesus. Finally, brethren, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is gracious, if there is any excellence, if there is anything worthy of praise, think about these things.
Colossians 3.1-3 If then you have been raised with Christ, seek the things that are above, where Christ is, seated at the right hand of God. Set your minds on things that are above, not on things that are on earth. For you have died, and your life is hid with Christ in God.
The second group are passages that MIGHT carry out the pattern or expand our understanding of it. I need to work through the first group, read those passages closely, to establish the pattern in detail. Then I will examine this second group and see if they add to our understanding of the pattern or if they are saying something else.
Romans 2.14-16 When Gentiles who have not the law do by nature what the law requires, they are a law to themselves, even though they do not have the law. They show that what the law requires is written on their hearts, while their conscience also bears witness and their conflicting thoughts accuse or perhaps excuse them on that day when, according to my gospel, God judges the secrets of men by Christ Jesus.
Romans 2.25-29 Circumcision indeed is of value if you obey the law; but if you break the law, your circumcision becomes uncircumcision. So, if a man who is uncircumcised keeps the precepts of the law, will not his uncircumcision be regarded as circumcision? Then those who are physically uncircumcised but keep the law will condemn you who have the written code and circumcision but break the law. For he is not a real Jew who is one outwardly, nor is true circumcision something external and physical. He is a Jew who is one inwardly, and real circumcision is a matter of the heart, spiritual and not literal. His praise is not from men but from God.
Romans 6.17 Thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed,
Romans 7.21-25 So I find it to be a law that when I want to do right, evil lies close at hand. For I delight in the law of God, in my inmost self, but I see in my members another law at war with the law of my mind and making me captive to the law of sin which dwells in my members. Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord! So then, I of myself serve the law of God with my mind, but with my flesh I serve the law of sin.
1 Corinthians 2.14-16 The unspiritual man does not receive the gifts of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. The spiritual man judges all things, but is himself to be judged by no one. “For who has known the mind of the Lord so as to instruct him?” But we have the mind of Christ.
1 Corinthians 10.6 Now these things are warnings for us, not to desire evil as they did.
2 Corinthians 10.3-6 For though we live in the world we are not carrying on a worldly war, for the weapons of our warfare are not worldly but have divine power to destroy strongholds. We destroy arguments and every proud obstacle to the knowledge of God, and take every thought captive to obey Christ, being ready to punish every disobedience, when your obedience is complete.
