There's a reason we don't often see things happening in the spiritual realm—it's too close to our face. But spiritual warfare is a reality of being a Christian, maybe more so now than ever. Looking at the story of the demon-possessed boy in Mark chapter 9, this encounter teaches us some important things about fighting spiritual battles. When engaging in spiritual warfare, the right diagnosis is essential. A lot of the time, things are what they seem, but if something can't be explained by something like illness, addiction, or circumstances, it could be spiritual. Our faith can be small, but it has to be dependent on God—in all circumstances, but for sure when it comes to fighting spiritual battles. And our biggest weapon in this fight? Prayer. In the war for our souls, you are a soldier for Christ.
