And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect will, of God.
Romans 12:2 (KJV)
When we renew our minds, we replace our thoughts with the thoughts of God, and we exchange our words for the Word of God. The more that we bring our thoughts and words into agreement with God’s Word, the more will we prove God’s good, acceptable and perfect will for us. And the way we prove it is to live it, to see it made manifest in our day to day lives.
