For to be carnally minded is death, but to be spiritually minded is life and peace.
A believer who is “carnally minded” is being controlled by their soul, which is their mind, will, and emotions. When you are being dominated by your soul, you are separating yourself from the new way of life God has for you to live. When someone is born again they receive a new spirit within that is now alive to God. The moment that happens God wants us to learn how to be spiritually minded, yielding our soul to our new spirit man. This is becoming spiritually minded.
Those who learn how to become spiritually minded, now dominated by the new spirit within them, they live in the life and peace God has provided. That word life is the word Zoe, and it means the God-kind of life. Your soul is made up of your mind, will, and emotions. Your mind is your human reasoning. When you allow your soul to rule you instead of your spirit man, you continue to live by the old adamic fallen nature instead of this new Zoe life of God.
To yield to this new spirit man within you must renew your mind to the Word of God, learning of this new spirit inside. You must develop your prayer life, allowing the spirit to dominate. You also need to be in church connected to a pastor who knows these things and can help you develop in this new life God has for you. The things of God must become a priority in your life or you will miss out on this new Zoe life and peace God has already provided within you.
