Several years ago I taught through the Book of Revelation in a couple of my Bible studies. It was when we arrived at chapters 11 & 12, we finally started hearing about beasts, dragons, etc.
This, quite naturally and appropriately brought up a discussion about Satan. Therefore, to help the conversation along, I shared the following “facts” on Satan that I gleaned from Wayne Grudem. I thought I might pass it along here as well.
Some Facts About Satan
1.) Satan was the originator of sin (Gen. 3:1-6; 2 Cor. 11:3; John 8:44; 1 Jn. 3:8)
2.) Demons oppose and try to destroy every work of God (Gen. 3:1-6; Matt. 4:1-11; John 8:44; Rev. 12:9; Ps. 106:37; 2 Cor. 4:4; Gal. 4:8)
3.) Yet, demons are limited by God’s control and have limited power (Job 1:12, 2:6; Jude 6; James 4:7). Wayne Grudem writes, “We should not think that demons can know the future or that they can read our minds or know our thoughts.” (Isa. 46:9-10; Mark 13:32)
With respect to knowing our thoughts, the Bible tells us that Jesus knew people’s thoughts (Matt. 9:4; 12:25; Mark 2:8; Luke 6:8; 11:17) and that God knows people’s thoughts (Gen. 6:5; Ps. 139:2, 4, 23; Isa. 66:18), but there is no indication that angels or demons can know our thoughts.
4.) There have been differing stages of demonic activity in the history of redemption…
5.) Are demons active in the world today? According to Grudem, “If Scripture gives us a true account of the world today as it really is, then we must take seriously its portrayal of intense demonic involvement in human society.”
6.) Not all evil and sin is from Satan and demons, but some is.
7.) Can a Christian be demon possessed?
It depends on what the person means by “possessed.” The New Testament doesn’t use this term in the original Greek. If by “demon possessed” someone means “that a person’s will is completely dominated by a demon, so that a person has no power left to choose to do right and obey, then the answer is “no,” for Scripture guarantees that sin shall have no dominion over us since we have been raised with Christ (Rom. 6:14, see also verses 4 & 11).
However, most Christians would agree that there can be differing degrees of demonic attack or influence in the lives of believers (see Luke 4:2; 2 Cor. 12:7; Eph. 6:12; James 4:7; 1 Peter 5:8).
8.) Jesus gives all believers authority to rebuke demons and command them to leave (Luke 9:1; 10:17, 19; Acts 8:7; 16:18; 2 Cor. 10:3-4; Eph. 6:10-18; James 4:7; 1 Pet. 5:8)
9.) We should expect the gospel to come in power to triumph over the works of the devil.
