I'm not sure when the term "spiritual warfare" was coined, but in my research I've discovered it mentioned as early as the 1600's.
Spiritual warfare is depicted (without using the term) back to the writing of the New Testament as Paul stated:
"Put on the full armor of God, so that you can take your stand against the devil’s schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms." (Ephesians 6:11-12)
For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. (2 Corinthians 10:3-5)
Here are 4 proven ways to stand strong in the face of spiritual warfare:
