In the sermon titled "Sound Mind," the Adam explores the concept of mental toughness through the lens of personal narratives and their profound impact on our mental health. There is power in the stories we tell ourselves about our past, present, and future and these narratives shape our identity and resilience more than our circumstances. The sermon is filled with truths that encourage us to adopt God's perspective of ourselves, viewing themselves as chosen, loved, and designed by God with a purposeful destiny. By aligning our internal stories with God's truth, we can foster mental toughness and live out our divine purpose.
