Do not conform yourselves to the standards of this world, but let God transform you inwardly by a complete change of your mind. Then you will be able to know the will of God—what is good and is pleasing to him and is perfect.
Romans 12:2 GNT
Man is created in the image of God, and the form of his mind is to be derived from Him and not from the things which are put in subjection under Him.
The man who conforms with this world is not the man who understands it best, or who admires its beauties most; nor can he adapt himself best to all its circumstances. On the other hand, the great peculiarity of the Christian method is transformation—not simply obedience to external conditions, but a renewing of the mind.
Remember that we need to know the will of God; do it persistently and patiently wait for the reward. Therefore, if we must understand the will of God, then we must allow God to transform our mind completely, then, and only then can we fully understand what the will of the Father is.
