“Do not be conformed to this world (this age), [fashioned after and adapted to its external, superficial customs], but be transformed (changed) by the [entire] renewal of your mind [by its new ideals and its new attitude], so that you may prove [for yourselves] what is the good and acceptable and perfect will of God, even the thing which is good and acceptable and perfect [in His sight for you]” (Romans 12:2, AMP).
God has a great plan laid out to reform you thinking. He already laid this out for each one of us so we will be able to think like Him and receive great ideas that are of Him. Yes, He is in the business of giving you a new attitude, which is the perfect will of God. Where there is sincere change there is Godly power and grace to be righteous -- reformed.
