What does the Bible mean by a 'form of godliness'?

According to 2 Timothy 3:5, those who have a 'form of godliness' present themselves with religious appearances and rituals, yet lack the transformative power of the gospel in their lives. This external display is superficial, ultimately serving to deceive others about the true state of their hearts. Such individuals may engage in religious practices, but their lives do not reflect the character of Christ or the resulting fruits of the Holy Spirit. Distinguishing between mere outward form and genuine faith is essential, as true godliness is demonstrated by a life transformed by Christ rather than by mere adherence to external religious practices.
