What if the real battle most people face is invisible? In this episode of Built on Behavior, Brooke Trometer sits down with Spiro Demetriadi, founder of Spiritual Combatives and author of How to Kill PTSD Before It Kills You. Drawing from decades of military training, martial arts, and faith-based study, Spiro explains why spiritual warfare is real, why mindset is survival, and how faith becomes a tactical advantage when life feels overwhelming.From the Battlefield to the Inner BattleSpiro Demetriadi has spent his life immersed in discipline, combat training, and survival. Military service, infantry training, airborne school, and decades working alongside elite law enforcement and military units shaped his professional path.But the most important battles of his life were not physical.They were internal.After years of helping others master tactics and physical defense, Spiro found himself facing personal loss and emotional hardship. That season forced a realization. Physical training alone was not enough. The spiritual dimension had been ignored.That realization became the foundation of Spiritual Combatives.What Spiritual Warfare Really MeansAccording to Spiro, spiritual warfare is conflict waged in the invisible spiritual world that manifests in the visible physical one. The battlefield is the mind.Negative thoughts, fear, hopelessness, self-doubt, and despair are not random. They are attempts to gain ground. While no one can stop thoughts from appearing, everyone has the power to choose which thoughts they allow to stay.You cannot stop birds from flying over your head.But you can stop them from building a nest in your hair.Detection matters. Response matters even more.Why Strength Alone Is Not EnoughSpiro emphasizes that physical strength without spiritual strength eventually collapses under pressure. He points to elite athletes, military operators, and high performers who break down not because their bodies fail, but because their inner foundation does.This belief is central to his book How to Kill PTSD Before It Kills You, written primarily for law enforcement, military, and first responders. The book reframes trauma through a spiritual lens, not as denial, but as preparation.His message is clear.God has your six.You are not alone, even when it feels that way.From Trauma to TrainingAfter a divorce and a season of deep sadness, Spiro immersed himself in scripture and spiritual study. What began as personal survival became a structured system.Over four years, he created the Spiritual Combatives Masterclass, a comprehensive program with more than 160 lessons and over 20 hours of training. The focus is not motivation, but transformation.Just as physical strength requires repetition, spiritual strength is built through daily discipline. Reading scripture. Challenging destructive thoughts. Reframing setbacks. Choosing gratitude even in pain.It is not about avoiding hardship.It is about refusing to be destroyed by it.Why This Message Matters NowLaw enforcement, military members, and first responders see humanity at its worst. Over time, that weight erodes faith, hope, and connection.Spiro addresses the stigma head-on. Vulnerability is often seen as weakness, but he believes it is the opposite. Strength includes asking for help.Heroes need support too.Closing ReflectionThis conversation is about awareness, not argument. About understanding that unseen battles shape visible outcomes. About recognizing that faith, discipline, and mindset are not abstract ideas, they are survival tools.Spiro leaves listeners with a powerful truth.You are already standing on the hilltop.Victory is not something you chase.It is something you defend.Connect with Spiro DemetriadiAll resources, courses, and service offerings:https://spiritualcombatives.com/fifthdimensionshowNew Book – U-Turn Your Life In 3 Days: Get Your Life Headed Back in the Right Directionhttps://www.amazon.com/dp/B0GBZH32HCU-Turn Your Life In 3 Days is a no-nonsense field guide for anyone who feels off-course, burned out, drifting, or spiritually worn down.
