Thank you for asking. Sorry that I took so long to reply. Such a complex question! It could be answered on so many levels that it’s hard to know where to start. I should preface everything by saying that I don’t believe in the myth of progress, in the sense that I don’t believe we, living in the 21st century, are any more moral or “good” than our ancestors. I also don’t believe that human progress in culture and morals will gradually usher in the kingdom of God on Earth. (The exact term for that escapes me at the moment, but I’m sure someone will supply it.)
With all those caveats out of the way, I would say that God charged humanity with culture-making, and progress has been made in that regard. But like all things human, everything we do is a mixture of good and evil, and every step forward is not necessarily permanent. Witness the rise of authoritarianism around the world.
As Christians, our kingdom is “not of this world,” since it is the kingdom of God. The worldview and culture that we are called by God to create should reflect the ultimate end – his kingdom. Paul described it in various ways, but ultimately it boils down to the fact that we are all one in Christ Jesus. Therefore, I believe we should work toward that goal now, all the while knowing we won’t reach it. By the same token, individually we work toward sanctification and maturity in Christ, all the while knowing we won’t reach it until the consummation.
Hope that made sense.
