Paul's letters to the Thessalonians are the earliest surviving Christian documents. They are also among the most easily overlooked parts of the New Testament. What could these short, simple letters possibly have to say to a world caught in the throes of racial discord, political polarization, fears of an uncertain future, and fights over truth and false news? While Paul and his companions could not have imagined anything like the twenty-first century, their letters in the mid-first century to non-Jewish followers of Jesus in northern Greece address problems we still wrestle with today: race and ethnicity, family, ethics, an unknown future, how to respond to strangers, and more. These letters, rather than being an outdated part of Paul's collected letters, provoke us to throw ourselves into the great challenges of the modern world, to resist the temptation to repay "another person evil for evil," and to "pursue the good, both for one another and for everyone" (1 Thess 5:15). Will we read these ancient letters anew?
