Throughout church history, the people of God have recognized that they need a strategy for overcoming opposition from Satan and his army of fallen angels, generally called demons, or evil spirits. This is most commonly referred to as ―spiritual warfare.‖ Spiritual warfare is generally considered to be the Christian encounter with these evil supernatural powers.
The original spiritual conflict was between Satan and God. Conflict began in the Garden of Eden as recorded in Genesis 3 and will continue until the fulfillment of events predicted in Revelation 20. Christians recognize that on the level of the heavenlies, the war has already been won decisively by God through the death, resurrection, and exaltation of Christ (Colossians 2:15; I John 3:8). Yet, on earth the battles continues, as believers in Christ face fierce and certain attacks from the Evil One and his helpers. In God‘s sovereign plan, our daily cbattless are not for the purpose of determining who will win, but to demonstrate whether as God‘s people we will appropriate the victory already won for us by Christ.
