Your charge is baseless. It is because I study the Scriptures that I reject your use of this passage in this discussion.
Paul says nothing about demons using objects to influence people. Paul says,
"Finally, be strong in the Lord and in the strength of His might. Put on the whole armor of God, that you may be able to stand against the schemes of the devil. For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. Stand therefore, having fastened on the belt of truth, and having put on the breastplate of justice, and, as shoes for your feet, having put on the readiness given by the Gospel of peace. In all circumstances take up the shielf of faith, with which you can extinguish all the flaming arrows of the evil one; and take the helmet of salvation, and the sword of the Spirit, which is the word of God, praying at all times in the Spirit, with all prayer and supplication. To that end, keep alert with all perseverance, making supplication for all the saints, and also for me, that words may be given to me in opening my mouth boldly to proclaim the mystery of the Gospel, for which I am an ambassador in chains, that I may declare it boldly, as I ought to speak." - Ephesians 6:10-20
The Apostle says, here, stand firm in Christ, hold fast to Jesus, remember our salvation, remember God's promises--stand boldly and hold to those promises, to the word we have received, that our faith shall guard us against the devil's lies. That the sufferings and troubles we face in the world does not lead us to have enmity toward men, but that the struggle is with the evils of this present age. The evils brought about by Caesar--even as Paul is in chains for the sake of the Gospel--does not mean that our contest is with the man Caesar Nero, or with Caesar's legions, or with the magistrates and governors--it is the wickedness, the tyranny of sin and death in the world, and the spiritual darkness which blinds men to the light of Christ and the peace and hope and redemption that is in Him, against which we struggle.
