Demonic Activity

Categories Theology Systematic Theology

Like God’s angels, Satan and his demons are active in the world today, and they work much evil. But they are not solely responsible for all the evil in the world. Much of the sin mentioned in the Bible is not the result of Satan or his demons but instead the result of an individual person’s own actions (James 1:14). Nevertheless, the Bible encourages us to “be sober-minded” and “watchful,” for “the devil prowls around like a roaring lion, seeking someone to devour” (1 Peter 5:8). Therefore, we are encouraged to “resist him” (1 Peter 5:9) and “give no opportunity to the devil” (Eph. 4:27).

As these attacks from Satan and his demons come in various forms and to various degrees, those who believe in Jesus should realize that through death, Jesus nullified the power of “the one who has the power of death, that is, the devil” (Heb. 2:14). And at the cross God “disarmed the rulers and authorities and put them to open shame, by triumphing over them” in Christ (Col. 2:15). Therefore, if Satan or his demons mount an attack against us, we should take confidence in Christ’s victory and use “the weapons of our warfare” that “have divine power to destroy strongholds” (2 Cor. 10:4). At times we may also decide to speak directly to an evil spirit, commanding it to leave in the name of Jesus (see Luke 9:1; 10:17; Acts 8:7; 16:18; James 4:7). We should not fear demons, for “he who is in you is greater than he who is in the world” (1 John 4:4). All the time we should “not rejoice...that the spirits are subject” to us but instead “rejoice” that our “names are written in heaven” (Luke 10:20).

In Romans 16:20, Paul tells Christians, “The God of peace will soon crush Satan under your feet.” As the good news of the gospel is preached and people come to believe in Jesus, another spiritual battle is won. And someday Christ will come and completely remove the influence of Satan and demons from this world (see 2 Thess. 2:8; Rev. 20:1 – 3).
