Episode Summary
What does it actually take to build emotional endurance instead of just pushing through stress until you burn out? In this episode of the God and Mental Health Podcast, executive leadership coach, TEDx speaker, and author Leslie Bosserman joins Roslyn to unpack the science and scripture behind her new book, Emotional Endurance: Faith-Fueled Skills for Bouncing Back. They talk through stress thresholds, emotional safety, capacity, and what it looks like to let God into the process of recovering from burnout instead of overworking your way out of it.
Scripture Referenced
- 2 Corinthians 10:5 — Leslie reads this directly: "We destroy arguments and every lofty opinion raised against the knowledge of God and take every thought captive to obey Christ." She uses this verse to frame the idea of taking unhealthy thoughts captive and inviting God into how we process emotions, not just what we decide to do.
- Leslie also references the Apostle Paul's teaching on wanting to do one thing and doing another instead ("that we will to do, that we do not practice") when discussing the gap between our intentions and our stress-driven actions. She does not cite a specific chapter or verse for this in the episode.

Key Topics & Takeaways
What emotional endurance actually is. Leslie describes emotional endurance as a dynamic capacity built over time, combining the science of hope, resilience, and strength psychology with a faith-based understanding that we're designed to be "kingdom builders." She's clear that anyone can build this capacity, whether or not they currently identify as a believer.
From residence halls to writing the book. Leslie traces her path from managing a 900-student UCLA residence hall, to building a coaching program at the University of Illinois, to becoming an early-adopter professional coach in her mid-twenties, to spending roughly a decade developing the framework that eventually became her book. She describes it as "a golden thread" — teaching what people needed, not what she planned to publish.
Curiosity versus judgment. One of the episode's central ideas is that curiosity is the antidote to self-criticism. Leslie explains that asking "what motivates you?" instead of "why did you do that?" opens a person up to understanding themselves rather than shutting down in judgment.
Understanding your stress threshold. Leslie unpacks the Yerkes-Dodson framework: stress improves performance only up to a tipping point, after which performance drops off sharply. She talks about helping clients identify their personal stress capacity and recognize what triggers them before those triggers "hijack" their best work and intentions.
Emotions as messengers, not marching orders. A recurring theme in the conversation: emotions are meant to inform us, not command us. Leslie describes letting an emotion "wash over you like an ocean" rather than dismissing it or letting it dictate behavior. Roslyn connects this to her own experience of hearing that emotions are "information," like a thermometer reading rather than a directive.
The emotion-to-character pipeline. Leslie walks through her coaching process: name the emotion, explore what's underneath it without diagnosing, decide how you want to feel instead, take that reframed thought captive, let it shape consistent action, and let that action shape character over time. She frames character as the lasting, "eternal" outcome of this work.
Rest, Sabbath, and capacity. Leslie shares that without a commanded, intentional Sabbath, she would never stop working. She discusses building sustainable rhythms of rest and renewal before burnout hits, and describes her own "timeout" practices — a glass of water, a walk, even jumping jacks — as ways to get back into her body during moments of overwhelm.
Defining capacity. Using the image of stretching a rubber band between your fingers, Leslie defines capacity as what you're able to handle before you break — and stresses that capacity isn't meant to be built alone. Asking for help, including relying on God, is part of expanding that capacity rather than a failure to have enough of it.
The six principles of the book. Leslie explains that Emotional Endurance is structured around six core principles, each paired with science and scripture and broken into three actionable skills, plus reflection questions and a companion book club guide. The book is designed to be read in any order, with busy parents specifically in mind.
Her own story with faith and timing. Leslie closes part one of the conversation by sharing her personal story of meeting her husband at age eight, staying close friends through their teenage years, and eventually marrying him at 27 — a story she uses to illustrate trusting God's timing over her own plans, and to reinforce the book's broader message about enduring through uncertainty with faith.
A struggle God strengthened her through, rather than removed. In part two, Leslie gets personal about raising her son Luke, who has autism. She describes him as her greatest teacher — present, authentic, and full of joy — and pushes back on the assumption that a special-needs diagnosis is only a hardship. She shares the "God story" underneath it: her husband Joel spent 22 years working in early intervention with children with autism before Luke was born, which Leslie frames as divine equipping rather than coincidence.
Reframing "good hard." Leslie talks about the mindset shift of separating what's hard from what's bad, and using difficult seasons to ask what God is building in her rather than trying to escape the discomfort. She ties this directly back to the idea that God's strength shows up in weak, unresolved moments rather than only after a struggle is removed.
Her personal spiritual and nervous-system practices. Asked what holds her together, Leslie names three core practices for this season of her life: slowing her internal pace through a daily walk (often praying or listening to scripture through the Dwell app, sometimes attending a yoga class instead), immersing her home in worship music, and treating writing itself as a spiritual practice and a way of creating from truth.
"Show up where you are." Leslie's closing piece of advice for anyone feeling burnt out or emotionally exhausted: no guidebook or prerequisite is required to come to God or to community exactly as you are. She encourages naming the hurt out loud, whether to God, a journal, a friend, or a partner, rather than waiting until you feel more put-together.
Book structure and release details. Leslie confirms the book released July 28th and describes its structure in more detail: 18 core skills organized around six foundational principles for developing emotional endurance, designed to be practical and immediately usable rather than purely conceptual.
