For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. - Romans 8:5 KJV
Romans 8:5 teaches us that if we “mind” the flesh, we will walk in the flesh. But if we “mind” the things of the Spirit, we will walk in the Spirit. Our actions follow our thoughts!
Let me put it another way: If we think fleshly thoughts, wrong thoughts, and negative thoughts, we cannot walk in the Spirit. It seems as if renewed, godlike thinking is a vital necessity to a successful Christian life.
Your life may be in a state of chaos because of years of wrong thinking. If so, it is important for you to come to grips with the fact that your life will not get straightened out until your mind does. You should consider this area one of vital necessity.
Ask God to help you learn to think thoughts that He would have you think. You cannot overcome any problem by determination alone. It is important to be determined, but determined in the Holy Spirit, not in the effort of your own flesh. The Holy Spirit is close to you. He is your Helper—seek His help. Lean on Him. You can make it with His help.
Give the Holy Spirit control of your life. He will lead you into the perfect will of God for you, which includes exceeding, abundant blessings, peace, and joy.
