The Spirit and the Flesh are totally separate species which are at odds against each other. As harsh as it sounds, their differences may be depicted like Heaven and Hell and has been spelled out clearly in Romans 8. 6. For the mind of the flesh is death; but the mind of the Spirit is life and peace.
Evident from our daily lives are those who are addicted to phonography, rampant uncontrolled sexual activities and desires, adultery, drugs, gambling, bullying, abusing, hating, lying, colluding, cheating, stealing, robbing, molesting, raping, etc will eventually spiral into unimaginable trouble and self destruction.
It is clear from the scriptures below that the Spirit and Flesh don’t mix. And it is mutually exclusive, where it is either or and never both. Romans: 8. 5. For they that are after the flesh mind the things of the flesh; but they that are after the Spirit the things of the Spirit. It is in the news everyday, that people who commit all sorts of crimes and immorality, are those that have no self conscious and Spirit bearing. For they are their own God and all the wrongs have been sanctified to become right.
According to the bible the choice between Spirit and Flesh has got its consequences. Choosing the Spirit will result in Godly gifts as in Galations 5:22 but the fruit of the Spirit is love, joy, peace, longsuffering, kindness, faithfulness. Whereas choosing the Flesh will not derive any Godly blessings and eternal salvation as portrait in Romans 6:23 For the wages of sin is death; but the free gift of God is eternal life in Christ Jesus our Lord and also in Romans 8. 10 And if Christ is in you, the body is dead because of sin; but the spirit is life because of righteousness.
Christians moves in the Spirit and lives with Holy Spirit, we are a reborn in the Holy Spirit as described in Romans 8. 9. But ye are not in the flesh but in the Spirit, if so be that the Spirit of God dwelleth in you. But if any man hath not the Spirit of Christ, he is none of his. And the Spirit of God that dwells in you is the same the Spirit of God that raised Jesus Christ up from the dead, which mentioned in Romans 8. 11. But if the Spirit of him that raised up Jesus from the dead dwelleth in you, he that raised up Christ Jesus from the dead shall give life also to your mortal bodies through his Spirit that dwelleth in you.
As Jesus followers we will also have the Spirit of God and Spirit of Christ in us and thus flow many giftings of the Holy Spirit. By the Word of God, we pray that we shall be good vessels for the Holy Spirit, abide by the guidance of the Holy Spirit and to never grief our Holy Spirit in us by pursing the Flesh.
