Having introduced this series as a guide to staving off those pesky demons, we continue by noting the divine reconnaissance we have from Ephesians 6:11-13.
It may be surprising to note that the first thing Paul explains in Ephesians 6 is that we are at war. It is dangerous to enter into combat without knowing the enemy, but God reveals everything that we need to know about the enemy in Scripture. The Apostle Paul begins his explanation of Spiritual warfare by giving a command to put on the full armor of God (Eph. 6:11, 13). Verses 11-12 give the warrant for this command. The reason we need to put on God’s armor is because we are in a war with Satan and demonic powers whether we acknowledge it or not.
The Devil is chief among the demonic powers in the universe (Eph. 6:11). He is described in Scripture as the ruler of the world (John 12:31, 14:30, 16:11). “[T]he whole world lies in the power of the evil one,” notes the apostle John (1 John 5:19). He rules over the domain of darkness (Col. 1:13), being the prince of the power of the air (Eph 2:2). In the beginning, he led a rebellion in heaven, taking with him one-third of the angelic beings God had created (Rev. 12:4, 7-10). At the end of the rebellion he was cast down to earth (cf. Luke 10:17-18). Like the angels who fell with him, Satan deceived the human race so that the human race would follow him in rebellion (Gen 3). Now, he runs like a roaring lion to destroy God’s people (1 Pet 5:9; cf. Job 1-2). Because of this, it is reasonable to conclude that Satan is a powerful being who garners respect and authority over the fallen angels.
