Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is,his good, pleasing and perfect will.
Romans Chapter 12: Verse 2
You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires;
to be made new in the attitude of your minds;
and to put on the new self, created to be like God in true righteousness and holiness.
Ephesians Chapter 4: Verses 22 - 24
Once you were alienated from God and were enemies in your minds because of your evil behavior.
But now he has reconciled you by Christ's physical body through death to present you holy in his sight, without blemish and free from accusation,
Colossians Chapter 1: Verses 21 - 22
