The world is made for natural creatures -  for flesh, for nature. So, disembodied spirits are out of place here. It's unnatural to be here without a body, without flesh to dwell in. Remember the curse God put on Satan -  "because you have done this, you are cursed above all cattle, and above every beast of the field, upon thy belly shall you go, and dust shall you eat all the days of your life".

"Eating dust" means Satan and all his demons, crave flesh -  they lust for it endlessly.  Anyone they influence also ends up lusting -  endlessly lusting,  for flesh. Their own above all else but also others. The lust of the flesh consumes their lives. The demons Jesus cast out of the man of the tombs, craved flesh so badly they begged Jesus to allow them to enter a herd of swine. Fallen spirits are addicted to fallen flesh. When we become a " new creation" in Christ Jesus -  demons will flee from the presence of Christ: but we must be filled with the Holy Spirit for the demons to stay away. Fallen flesh has no defence against fallen spirits, indeed, they are not even aware of them. One of Satan's most successful strategies is to convince people he doesn't exist. A Christian's only defense is to give his flesh to the Lord -  to make it "holy ground " -  by inviting the Holy Spirit to inhabit  soil (dust) Satan and his cohorts used to eat. Satan, and his own, whether demons, devils or human spirits -  eat "flesh" all their days: they consume fleshly desires and lusts. Christians too "eat flesh" -  but we eat Jesus' flesh. Every time we take communion we're reminded of this. We survive as saints on His flesh, not our own. In other words, we no longer consume fleshly lusts and desires (and are no longer consumed by them) rather, we consume Christ's love -  his fruit. We are motivated by his desires -  we give and not take, we bless and not curse, we love and not hate. 

We become righteous (flesh) and no longer unrighteous (flesh). Remember Mark 16:16? "He that believes and is baptized shall be saved". All my life i thought Jesus was speaking of water baptism. I personally love the ceremony of water baptism. The symbolusm. The public witness, but i always had a nagging question  - wow Lord, You sure put an incredible emphasis on water baptism.  I mean, if someone believes the Gospel but somehow doesn't get baptized before they die, they won't be saved? God has opened my eyes to this truth: Jesus is referring to the baptism of the Spirit -  not water baptism alone.

"And I knew him not: but he that sent me to baptize with water, the same said unto me, upon whom you shall see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost ".
