The thing that smacked me in today’s reading (Revelation 9) was at the end when (twice) it says that they “did not repent.” When you read everything that leads up to those verses you’re thinking, “Okay, if this won’t make people repent, nothing will.” And then the people who experience all that … don’t repent.
And I think it just goes to show that some people will not turn to God no matter what. You could engineer the most repentance-producing circumstances the world will ever see (a.k.a. Revelation 9) and still … no repentance. That is heart-breakingly sad (even more for God than for us), but none-the-less true.
