What is vain religion according to James?

James distinguishes between pure religion and vain religion, the latter being devoid of divine power and rooted in human effort. Vain religion arises from a deceived heart that engages in empty practices, claiming righteousness while lacking genuine transformation (James 1:26). It often manifests in outward appearances and rituals but lacks the substance of true faith. This kind of religion cannot please God, as it operates outside the grace of Christ, failing to recognize the need for a heart change that comes through the gospel.
