As you pray for the Holy Spirit to make you aware of thoughts that come into your mind that don't line up with God's Word, you'll begin to realize when those thoughts come and you can renew your mind with the Word.
When the mind changes the outer expression must change to correspond. We are transferred by the renewing of our minds.
Put on the new man by renewing your mind with God's Word and submitting your body to the authority of that Word.
Age is an issue of mind over matter. If you don't mind, it doesn't matter.
God desires to change us from the inside out. Renewing our minds, starving our self-destructive tendencies, and teaching us to form new habits.
