If it were possible for us to "bind" Satan today, we would not need instruction about the various pieces of the armor of God. If Satan could be bound, he would not be capable of attacking us and throwing flaming missiles. In fact, the concept of "binding" Satan can actually be quite a dangerous belief. If we believe that we can "bind" Satan, we will (wrongly) think that he has been incapacitated, and we will be completely unprepared for the enemy's attacks. In addition, if we believe that our prayers can "bind" Satan, we will be far less diligent about "putting on God's armor," and will be defenseless and vulnerable to Satan's attacks. Satan is not bound – and cannot be bound at the present time. Our strategy, then, is to be fully armed to repel his attack. Putting on the armor of God and fighting is the kind of resistance that thwarts the enemy's scheming tactics, and forces Satan to flee.
