Why is so much attention paid to the opulence of Persia in the first half of Esther chapter 1; and is there any message in that section for us today. You will be riveted on the story of Ahasuerus, and even more riveted by the REST of the story.
While living under house arrest (probably in Rome), the apostle Paul writes a brief letter to the Ephesian and surrounding churches. His point is to remind them how to live as a marginalized minority in the midst of a pagan and pluralistic society: they must recognize that they're a new humanity in Christ. By the free grace of God they've been set apart for salvation. They must rejoice in that hope and live in a manner that's consistent with that calling.
