Romans 12:1

And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is good and acceptable and perfect will of God.

Our minds are like a rudder on a ship with our thoughts steering us where we go.  When we renew our minds to the word of God we clean out the junk of the world…fear, sadness, poverty mindset, and anger.  God has a perfect will for our lives, and we become open to His leading by being transformed by the word. We are transforming our minds from the negative things of the world to the life-affirming thoughts of God.
