In this episode of the Fast to Faith podcast, Dr. Tabatha Barber (triple‑board‑certified functional‑medicine physician) hosts Dr. Russ Irwin (psychologist, neuroscientist, and faith leader) and producer Ashley. The conversation weaves together neuroscience, psychology, and Christian faith to explain how trauma is stored not as a narrative but as a physiological state in the nervous system. They differentiate PTSD from CPTSD, describe the brain regions (amygdala, hippocampus, limbic system, pre‑frontal cortex) that drive hyper‑vigilance, survival dominance, and fragmented memory storage, and explain how triggers reactivate these subcortical layers. The dialogue moves to the concept of “identity foreclosure,” where trauma hijacks self‑concept, leading to shame, guilt, and confirmation bias. Dr. Irwin and Dr. Barber discuss neuroplasticity, the restorative aspect of the Gospel (Makashavod, renewing the mind), and practical spiritual‑psychological tools—coaching, gratitude, fasting, and neuro‑spiritual practices—to rewire the brain, reclaim identity, and achieve post‑traumatic growth. The episode ends with encouragement for listeners (especially women) to seek mentorship, embrace willingness, and view healing as both scientific and divine.
