Culture represents the values, traditions and behaviors of a society, and though culture is improvable, it is not perfectible. And even where positive change occurs, it’s difficult to perpetuate, largely because the people needed to sustain the change are few, flawed and temporary. A society’s culture is no better or worse than its leaders and the citizenry who support them; and at the heart of every problem is the problem of the heart. Apart from regeneration and a transformed mind and will, people will default to selfishness and sin, and so social problems continue. Furthermore, if we did make great improvements, we cannot guarantee succeeding generations will follow the good pattern set for them. Below is a NT example in Acts 19 of how the city of Ephesus was improved culturally from the bottom up, as a result of the apostle Paul’s preaching the gospel and biblical teaching over several years.
