This is a very important statement. Every Christian is required to walk in the Spirit. It is when you walk in the flesh that you get yourself in trouble. Walking in the Spirit sets you apart from the things of the flesh, the things of the world that desire to control your life. We must first define what it means to walk in the flesh. Then we will define what walking in the Spirit means.
Matthew 26:41, "Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak."
In this passage Jesus is in the Garden of Gethsemane praying. He speaks to the disciples and tells them to watch and pray so that they would not enter into temptation. Here He makes a clear distinction between the flesh and the spirit. The flesh He calls weak, however regarding the Spirit He calls it willing. It seems that the flesh nature of man is where wicked temptations find their ability to function. It also seems that it is when the spirit of man is strong towards God that temptations lose their power to sway believers. What therefore is this flesh thing? Paul spoke about this, let’s take a look at what he said regarding the flesh. As you can see from looking at Matt 26:41 the spirit of the man desires to do right, but it is the flesh that is weak and causes man to sin. Therefore it is necessary that we understand how to escape the power that the flesh has over our lives.
Romans 7:14-24, "For we know that the law is spiritual: but I am carnal, sold under sin. For that which I do I allow not: for what I would, that do I not; but what I hate, that do I. If then I do that which I would not, I consent unto the law that it is good. Now then it is no more I that do it, but sin that dwelleth in me. For I know that in me (that is, in my flesh) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. For the good that I would I do not: but the evil which I would not, that I do. Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me. I find then a law, that, when I would do good, evil is present with me. 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 sin which is in my members. O wretched man that I am! who shall deliver me from the body of this death?"
In Romans 7:14-24 Paul begins to outline the nature of the war between the flesh and the Spirit. He states that the law is spiritual. However, he also goes on to state that he is carnal, sold under sin. Let’s take a moment to define these two words.
spir·i·tu·al (sp¹r¹-ch›-…l) adj. 1. Of, relating to, consisting of, or having the nature of spirit; not tangible or material. (American Heritage Dictionary)
SPIRITUAL: 4152 pneumatikos {pnyoo-mat-ik-os'}
1) relating to the human spirit, or rational soul, as part of the man
which is akin to God and serves as his instrument or organ
1a) that which possesses the nature of the rational soul
2) belonging to a spirit, or a being higher than man but inferior to God
3) belonging to the Divine Spirit 3a) of God the Holy Spirit
3b) one who is filled with and governed by the Spirit of God
4) pertaining to the wind or breath; windy, exposed to the wind, blowing
The word spiritual defined means something that comes from and is operated by God. Something that is not material or tangible. Paul therefore is saying that the law has the nature of the spirit of God. The law is governed by and was released by God. Now let’s look at the word carnal.
car·nal (kärn…l) adj. 1. Relating to the physical and especially sexual appetites: carnal desire. 2. Worldly or earthly; temporal: the carnal world. 3. Of or relating to the body or flesh; bodily: carnal remains.
CARNAL: 4559 sarkikos {sar-kee-kos'}1) fleshly, carnal 1a) having
the nature of flesh, i.e. under the control of the animal appetites
1a1) governed by mere human nature not by the Spirit of God
1a2) having its seat in the animal nature or aroused by the
animal nature 1a3) human: with the included idea of depravity
1b) pertaining to the flesh 1b1) to the body: related to birth, linage, etc
The word carnal in contrast to the word spiritual deals directly with the desires of man and does not possess the nature of God. This word represents the appetites of man, which are governed by man’s own personal wants. God does not deal with the flesh nature of man it is His enemy. Notice the passages below:
Romans 8:7, "Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be."
Rom 8:7 Our desires fight against God, because they do not and cannot obey God's laws. Rom 8:8 If we follow our desires, we cannot please God. Rom 8:9 You are no longer ruled by your desires, but by God's Spirit, who lives in you. People who don't have the Spirit of Christ in them don't belong to him. (Contemporary English Version)
