By flesh I am referring to both our carnal nature and our physical human body, together with our hearts and emotions (just everything that has to do with being human).
"That which is born of the flesh is flesh; and that which is born of the Spirit is spirit." (John 3:6).
"The first man is of the earth, earthy: the second man is the Lord from heaven. 48. As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly." (1Cor 15:47).
Firstly we were born as Adam, but then we met the Lord and was born again from above. We were born again not of flesh or anything earthly, we were born heavenly as a people of the second Adam, the new man, the one who transcends all that is earthly.
"And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:" (Eph 2:6).
We were raised together with this second Adam to be seated with God in the heavenlies. The first Adam was created to have dominion over all that is earthly, he failed. Then came the second Adam, conquering the flesh, the devil and his power—death. And now we are seated in him, on the throne of victory, a throne far above that which is flesh and earthly.
What I am simply trying to say is that you are beyond this flesh, you are beyond flesh and blood. You have transcend all that is flesh and earthly. Your spirit is born of God but your flesh is born of the first Adam. The real you is heavenly, it is spirit, and it is seated in heaven reigning over all that is earthly, including your flesh.
"bringing into captivity every thought to the obedience of Christ;" (2Cor 10:5).
You are meant to reign over your flesh and bring it to obedience. Yes, to bring your thoughts, emotions and every urges or desire of the flesh to obedience. You are not a slave to your emotions or your flesh. The real you (spirit) is seated on the throne where all the authority in heaven and on earth resides. You have enough power and authority, you are well capable of bringing your flesh to obedience.
We need to stop thinking like dead men. Adam was created to rule over all that is earthly, but then he sinned against God and died, as a result the very thing he was created to rule rebelled against him. The earth became stubborn, afflicting Adam with struggle and suffering before he can eat of its fruit. It rebelled against Adam and started giving him thorns and thistles, instead of edible food.
The animals rebelled against him and started devouring man. The plants also rebelled; some became poisonous and some grew thorns and spike to harm man. Even Adam's flesh rebelled against him, it enslaved him and started ruling him. This is how low man stripped as a result of death, but Jesus came to redeemed man. By regenerating our spirit, he made us to sit above all things, restoring us back to live and giving us a greater dominion than that which Adam lost.
Now we would not only rule over that which is earthly, we would also rule over the heavens. He gave us enough power and authority to take this rebellious earth and flesh and bring it to obedience. Yes, we are to bring our rebellious flesh to obedience. You cannot have dominion on the earth if you do not have dominion over your own flesh.
Don't allow yourself be ruled by your emotions, even your innate traits shouldn't rule over you anymore. You are no longer that old person, you have become a new creation, old thing are pass away. You are a new man born from above. Stop giving silly excuses such as, "I am just a man... That is just the way I am, it is in my traits, my father is also like that, there is nothing I can do about it".
Yes, your father gave birth to a person, and this person has all these short comings and weaknesses, but this person is dead. You died, and now a son was born in heaven and it possesses this body. You are that son, you are not a slave to your body. The way Christian acts, it's like an alien movie, where the aliens came and possess human bodies, but then they get so overwhelmed by the emotions and life of that human they possess that they forget they are alien.
Rather than possessing the body, the body end up possessing them, it override their nature with its own nature and start ruling them. I don't know why we think it is normal to be rule by the nature of your body? You are not that flesh anymore, that person with that character and that nature died, and you were born from above and you possess this body.
You are a completely different person, do not allow the flesh you are meant to rule possess you. No, it is not meant to possess you, you were meant to possess it and bring it to obedience to Christ. You are one with Christ now, your true nature is Christ, everything about you is Christ, so bring this flesh to the obedience of who you really are. Reign in this flesh and don't let your body reign over you.
I didn't plan this post to be this long, but the vexation of the Spirit against this enslavement is much. May you walk in victory.
