Philippians

Thought this blurb from a Bible Dictionary was lovely:

"The joy caused by his return, and the effect of this wonderful letter when first read in the church of Philippi, are hidden from us. And we may almost say that with this letter the church itself passes from our view. To-day, in silent meadows, quiet cattle browse among the ruins which mark the site of what was once the flourishing Roman colony of Philippi, the home of the most attractive church of the apostolic age. But the name and fame and spiritual influence of that church will never pass. To myriads of men and women in every age and nation the letter written in while he was under house arrest in Rome, and carried along the Egnatian Way by an obscure Christian messenger, has been a light divine and a cheerful guide along the most rugged paths of life"
