This is important: Satan has lost already!
Colossians 1:9-14 We have the power to resist him. The more we know how he works the better we can defend against him. When his target is our mind, he lies. His goal: to get us to doubt God and to not believe Him. When his target is our body, he can bring on suffering. Not all suffering is from Satan, but when it is his goal is to us our suffering to turn away from God–to separate us from Him and from others.
We can respond. We can defend against his attacks. We have tactics that can defeat and resist our Enemy. Learn what they are!
