Turns out some silversmiths were pretty concerned that this new Christianity thing might really catch on. Not that they were that worried about their business or anything.

Or presidential campaigns.

But we can stop and make sure we aren't running headlong behind them, not knowing why we're even there. To the contrary, just across the Aegean Sea, the Bereans were called noble because they searched the scriptures to see if what they were hearing was sound. (Acts 17:10-11)
