The Greek and Hebrew words that are translated as "mind" are also translated into several other words that seem to indicate that the concept is that of the mind or soul of the person--that is, the inner person, the mind/soul/heart/life/self as opposed to the human spirit or the human body/flesh.  The words, mind, soul, heart, life, or self are all synonyms for this part of our 3-part beings. It is the word that is used for a person's will or pleasure, which resides in the soul/mind. It is the life of the person--when the soul/mind leaves that body, the body dies. The brain is there in the body, but the mind has left.

The Holy Spirit has shown us, through Scripture, that we are three-part beings: spirit, soul/mind/heart/life, and body: More info here  We were created spirit, mind, and body. A naturalist will say that the brain is the mind, but the brain is part of the body and there is no scientific evidence that the brain, wonder that it is, would ever be capable of thought as the mind can think.

The same word that is translated as soul is also translated as heart, life, and mind.  The battle, once you are born again, is for the mind.  Satan wants to control the mind through the flesh, the body--through emotions and the functions of the brain and nervous system.  Our spirits are having a great measure of unity with the Holy Spirit--in fact, we are seated in heavenly places with Christ Jesus.  The Holy Spirit is the One Who ought to be controlling our minds.  As Paul said, to be carnally minded is death and to be spiritually minded is life.  This all ties into salvation by grace through faith.

The human mind naturally contains a paradigm, a fake reality.  The easiest way to understand this is through your own paradigm.  Just now, think of your bedroom; do you have a drawer in your bedroom?  Can you open that drawer in your mind and see what is in that drawer?  You didn't actually open it, but you were dealing with your own paradigm.  Paradigms have a mix of truth and error.  The paradigm is like a garden full of weeds.  The Holy Spirit pulls the weeds and plants the right kinds of plants that grow the right kinds of fruit.

As with so many topics, we really need to understand what the words mean in order to understand the concept.  By doing a word study on any of these Greek or Hebrew words, we see that they can have quite a broad range of meanings depending on context.  They can, for instance, sometimes be used as a reference to the being of an animal.  Some of these words are used to refer to the mind or soul of God, Himself.  They can be used to express killing as the taking of a life or the fact of being alive.  It it very striking that the nature of the soul or mind is that it is the very life of the person.  This is the place desires come from, though the word, heart, seems to sound better when we think of that.  It is where hunger or thirst are recognized within us.  Understanding this word can give us a better understanding of what we are actually reading in Scripture and what we actually are as human beings.

Definition of  real faith and real grace.
