“Owe no one anything, except to love one another; for the one who loves another has fulfilled the law.” (Romans 13:8)
I had to check to see what the context was for verse 8; no, beloved reader, I do not have scripture memorized. Paul, in verse 7, had exhorted his readers to pay to all what is due to them. Verse 8 then exhorts us to let ourselves in debt to any one except for the debt of love. Now, this does not mean financially – at least I hope not, but it very well may. Our modern society does not seem to be set up for “pay as you go”. It is, however, a different type of society than the one Paul lived in. There and then, being in financial debt to another may impinge on their livelihood, or endanger one’s own welfare. So you can see why Paul might be anxious that his readers not incur debt. . . .
