True religion, as defined by James, is not measured by outward religious performance but by inward transformation evidenced in a bridle of the tongue, active compassion toward orphans and widows, and a life marked by moral purity and separation from the world's corruption. The sermon warns against the deadly deception of self-righteousness, where one may believe they are religious while their uncontrolled speech and lack of tangible love reveal a faith that is worthless before God. Drawing from Scripture, it emphasizes that God's standard of purity is absolute, and that genuine faith inevitably produces actions that reflect Christ's heart—especially toward the vulnerable and marginalized. The call is not to legalistic rule-following but to a life transformed by the gospel, where holiness is pursued not by human effort alone but through the cleansing blood of the spotless Lamb. Ultimately, true religion is not about religious appearance but about being changed by God's grace and living in faithful obedience to His commands.
