The devil is a reality who oppress us. The same is true of demons. However, their knowledge of things and power are certainly not unlimited. Not every perceived spiritual attack is directly caused by Satan. He can only do as God permits him. What Scripture tells us to do is draw near to God (James 4:7-8). If we do that, then the devil will flee from us because God draws near to those who seek after Him.
We are to put on the armor of God (Ephesians 6:10-18). That Pauline passage employs imagery of the armor that Roman guards wore. Our chief concern in this life should be serving God according to His will and not continually rebuking or binding the devil. We must turn to the guiding principles provided in God-breathed Scripture (Matthew 4:1-11; 2 Timothy 3:16-17).
