The apostle James also mentioned something about spiritual warfare in his epistle. Did he tell the Christians that their prayers could determine the outcome of angelic battles? No. Did he tell them to pull down the spirits of lust, apathy, and drunkenness over their cities? No. Did he tell them to study the history of their cities so they could determine which kind of evil spirits have been there since the beginning? No.
James believed in scriptural, spiritual warfare, and so he wrote:
Submit therefore to God. Resist the devil and he will flee from you (James 4:7, emphasis added).
Once again, notice that the Christian’s posture is one of defense—we are to resist, not attack. When we do, James promises us that Satan will flee. He has no reason to stick around a Christian who will not be persuaded to believe his lies, follow his suggestions, or yield to his temptations.
Notice also that James first instructed us to submit to God. We submit to God by submitting to His Word. Our resistance against Satan is predicated upon our submission to God’s Word.
