There were 2 parts of Acts 18 that really stood out as I read them, and I'll share one with you:
The message of Jesus was spreading through Ephesus (as it was elsewhere) and part of that message was that "man-made gods are no gods at all". In other words, idols were worthless. A silversmith called together other workman in related trades and got them angry because they were losing business because of this belief. So, a riot broke out and...
"The assembly was in confusion: Some were shouting one thing, some another. Most of the people did not even know why they were there." Acts 19:32
That's hilarious, but not suprising, to read that many people were there and didn't even know why. They were just there for the show. It was like a first century Jerry Springer episode. People will always gravitate toward things they don't fully understand, but eventually support them. Churches have to deal with that on both sides, being sensitive to beliefs (or disbelief) that someone may have from following a crowd while making sure the church itself doesn't follow a crowd and end up standing strong for something the Bible doesn't specifically take a stand for (or against).
What do you strongly believe in, or against, but have never examined why you believe that?
