A good essay here from a few years back by David VanDrunen of Westminster Seminary California. He argues (correctly I think) that there’s no better place to look in Scripture for a biblical understanding of culture than Jeremiah 29. Money quote:
Two extremes they were to avoid. First, they were not to shun involvement in pagan Babylonian culture. Second, they were not to become so involved that they lost sight of their true destiny or the true destiny of Babylon. Instead, they were to do their various cultural tasks, building homes, planting farms, raising families, while all along recognizing the temporary and limited nature of the work they did.
