In the kingdom of God, enemy territory is any territory outside of God's will and purpose. If you know that the Lord God Almighty desires that you do something, and instead, you do the opposite, you enter into enemy territory.
In enemy territory, anything and everything is possible. You not only are in danger physically, spiritually, and emotionally, you also are in danger ethereally, which means that you can lose your place in heaven's ether. Instead of being raptured, you will have fallen to a lower level.
