In this sermon on Romans 12:1–2, Pastor TJ picks up after eleven chapters of theology to ask what it actually looks like to respond to God's mercy: presenting your whole self as a living sacrifice. He challenges the compartmentalized, "Sunday only" Christian life, arguing that no part of our lives is untouched by the gospel — even the mundane can glorify God. He then offers practical diagnostic questions for spotting where the world is quietly conforming us, from sin and screen time to patterns of neglect. Finally, he shows how real transformation comes through a mind renewed by Scripture, not an inward journey of self-discovery.
