It has been correctly stated that Christians are in a constant war. And in this war, we have three main enemies; the world, the devil, and our unregenerated flesh.
The Bible teaches that we, humans, are spiritual beings that have souls and who live in physical bodies. In other words, we consist of three parts; spirit, soul, and body. “And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.” (1 Thessalonians 5:23, KJV).
Some view the soul and spirit as being the same thing, but this is not true. Both soul and spirit are part of the “inward” person, but they are clearly separate. “For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discernier of the thoughts and intents of the heart.” (Hebrews 4:12).
When we were born again, our spirit was recreated and bonded with God’s Spirit. So, the new birth refers to our spirit. The remaining two parts of us, the soul and body, were not born again. These two parts remain in an unregenerated state. Many difficult Bible passages can be more clearly understood if you realize this fact. At times, the Bible speaks directly concerning our spirit but not to the soul or body. “Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.” (1 John 3:9). The part of us that was born of God, our human spirit, cannot sin. We sin from the part of us that was not recreated during the new birth.
We see in scripture that the “born again” part of us is in a constant battle against the unregenerated parts of us. Even the Apostle Paul had this problem. “For I delight in the law of God after the inward man: But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of which is in my members.” (Romans 7:22,23).
The part that we give the most attention to is the part of us that will dominate our lives. If we neglect the things of the spirit and continually embrace the things of the flesh, we will be flesh dominated. However, if we crucify our flesh, that means to deny its ungodly desires, and sow to our spirit, we will be dominated by our born again spirit.
In order to be spiritually victorious in life, we must live a spiritual life. We have to spend time in God’s word and in prayer. We have to embrace the fruits of the spirit and fight against the lusts of the flesh. There is an old saying that basically says that everyone has two dogs fighting on the inside of them. The one that is fed is the one that will win. And the one that is starved is the one that will grow weak and lose. Follow after the things of the Spirit and you will have victory over your flesh. You will see more of God’s power manifested in your life when you are spiritually dominated.
