This means to be sober-minded has to do with maintaining control over ourselves. Just like when someone drinks too much alcohol, they have to “sober up” to regain control, to be sober-minded means regaining control over our actions and reactions. Remember, we have an enemy who doesn’t just want to tempt us—he wants to devour us. He wants us to act and react out of control. And he wants our thoughts to spin out of control.
