Satan’s only weapon against us is creation. He uses physical things to get people to fail spiritually. Satan is a creature, he does not have spiritual power per se, but he does have power to warp people spiritually.
Knowing that Satan uses physical things to keep us from God, what should our relationship to physical things be? We are kind of dependent on them to sustain our physical lives.
First off, don’t be too enamored with life. This involves laying hold of eternal life, setting your mind on things above, not on things of this world. Don’t entangle yourself with the affairs of this life, see yourself as a citizen of heaven.
Our relationship to physical things determines our spiritual health. You can’t serve God and Mammon. Romans 1 says what makes God harden a heart is when people worship the creation over the Creator who is blessed forever, amen.
Our physical desires and lusts are given by God and have a set way to be used. But what God purposed for good, Satan desires to distort and make hideously evil. Crucify the flesh with its affections and lusts in Christ and rise up to newness of life lived on a spiritual plane Satan can never touch!
