Romans 12:2 refers to renewing the mind. This applies to every level you're walking at, whether talking about healing, sin or any area. If you will put this into effect, the Word of God promises you that your life will be changed. Ephesians chapter 4, verse 23 says, "And be renewed in the spirit of your mind." Many say the right things and believe this is having their mind renewed, but you have to go beyond renewing the mind to renewing the spirit of the mind. The spirit of the mind is referring more to the positive and negative aspects-for example, quoting the Word but expecting the worst.
