“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)
Renewing of your mind – what does that mean? Does that mean that you continuously and slowly reform your mind? Does that mean that you thought by thought make your mind better? Renewing of your mind happens on the cross. It happens once, when you are buried and resurrected in Jesus Christ! After you have a brand new mind, then your mind is renewed every day, because you grow in your new mind. The old mind has to be put to death, and the new mind has to be born again. That is the teaching of Jesus Christ. But what is your mind? Is your mind in your head? Your mind is actually in your heart. It includes understanding, knowledge, judgement, thoughts, and all of those things come from your heart.
I always found it interesting, why the Bible is split into two, why there is an Old Testament and a New Testament. Behind these testaments, stand a covenant. I like to think of these covenants as being a model for our relationship to God. In what position are we in relationship to God. It is important to understand these models and how they are different.
