Let's talk about the mind, specifically from the book of Romans.
God does not want you to be brainwashed.
God does not want you to be a mindless puppet.
God does not want you to be a soulless, spiritless, emotionless, dead machine.

Romans 12:1-2
I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service. 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.
