There is likewise this element of danger in the Christian life about which Paul cautions the Ephesian church. It is a danger that is not just from within ourselves, but that also has a particular, specific external source: a spiritual entity we call Satan (“the accuser”), or the devil. We know this because in verses 11-12 Paul says that the reason for putting on the full armor of God is so 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 spiritual forces of evil in the heavenly places.”
