Spiritual warfare is a reality affecting all believers, with Satan functioning as our adversary who actively seeks to harm us. Being sober-minded means recognizing this threat and taking it seriously, much like a vigilant Marine searching for hidden dangers. The enemy primarily attacks through accusation and slander, constantly suggesting negative thoughts that contradict God's truth. Though defeated at the cross, Satan still has the power of suggestion, attempting to redirect our thoughts and destroy our faith. Resistance comes through standing firm in faith, staying connected in community, and remembering that greater is He that is in us than he that is in the world.
