Proverbs 4:23 (NCV)
Be careful what you think, because your thoughts run your life.
There are two primary sources from which thoughts are generated: the physical realm and the spiritual realm. The spiritual battle is between the physical realm (what the five senses are telling you) and the spiritual realm (what God’s Word is telling you). From the day you were born physically, you were programmed to think according to your five physical senses, but now that you are born again spiritually, you should start thinking according to God’s Word.
Everything you need for the rest of your life already exists in your re-created spirit. Manifesting in the physical realm what already exists in your re-created spirit is called living out of your re-created spirit. Once you are born again, the rest of your Christian life is learning how to live out of your re-created spirit.
The direction your thoughts take you is determined by the thoughts you allow yourself to entertain. It is your responsibility to do something with the thoughts that come into your mind. Any thought that opposes the knowledge of God should be discarded and replaced with an image of God’s new creation picture of you. You are to replace every thought that opposes the truth of God’s Word with thoughts that conform to the reality of who you are in Christ. An obedient thought life is one that focuses on who you are, what you have, and what you can do because you are in Christ. An obedient thought life is one that agrees with your re-created spirit.
