Spiritual warfare
Spiritual warfare is a Christian belief of fighting against bad supernatural forces (demons). The existence of bad spirits which can affect humans is the main idea for this belief system. Many Christian groups have used ideas of this movement to hold back these bad forces. These ideas mainly come from Christian demonology. A way to fight these forces is by using prayer. Exorcisms (removing demons), laying-on of hands, fasting, or anointing with oil are also used.
