“that is why it depends on faith, in order that the promise may rest on grace and be guaranteed to all his offspring—not only to the adherent of the law but also to the one who shares the faith of Abraham, who is the father of us all,” Romans 4:16

“Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God.” Romans 5:2

“For by grace you have been saved through faith.” Ephesians 2:8

 Paul talks about the importance of our minds later on again in Ephesians 4:20-24

“But that is not the way you learned Christ!— assuming that you have heard about him and were taught in him, as the truth is in Jesus, to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness.”

He here stated that by renewing our minds we put off the old self and put on the new self… sounds something like Romans 12:2

“Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.”
