How do we know that the gospel changes lives?

The change brought about by the gospel is profound and life-altering, as shown in Acts 19. The conversion of many Ephesians from idol worship to faith in Christ led to a public outcry from craftsmen who profited from idolatry. This event underscores the reality that true acceptance of the gospel results in changed lifestyles and priorities, often provoking resistance from those whose livelihoods depend on false religions. The gospel not only affects personal belief systems but also societal norms, demonstrating its transformative power on a community level.
