In the battle for your mind, we dig into the details of the process of transformation for the Jesus follower into the image of Christ. Scripture reveals that since the Jesus follower is indwelt by the Holy Spirit, they have been given a renewed mind. As new creatures in Christ, the Jesus follower have a new capacity for thinking. They begin to thinking biblically. They begin to obeying the teachings of Scripture. They find a need to reject and abandon the old ways of thinking and replace them with new ways of thinking. Hence, the value and importance of a new mind. The Scripture describes this process as a put-off and put-on exercise. As knowledge of the Scripture grows, discernment grows. This discernment that comes through the renewed mind guides the Jesus follower in knowing what to put off and what to put on. 

And be renewed in the spirit of your mind. (Ephesians 4:23 KJV)

Do not conform 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 12:2)

Lie not one to another, seeing that ye have put off the old man with his deeds; And have put on the new man, which is renewed in knowledge after the image of him that created him. (Colossians 3:9-10)

The Jesus follower with their renewed mind is prepared to obey the first commandment by loving the Lord their God with all their mind. 

Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength. (Mark 12:30)
