I may be able to tell you the lineup of the 1990 Cincinnati Reds. I remember how it felt in the stadium when Adam Dunn hit a walk-off grand slam in 2006 against the Cleveland Indians. I can tell you when and where I was when Jeremy Hill fumbled in a playoff game for the Cincinnati Bengals in 2016. There's countless more instance and details I know. In the long run... these don't have much eternal value.
Jesus is pointing out to his listeners that they know the weather very well. But are they paying attention to the Kingdom of God? Here is the Messiah, and they're missing the signs because they're paying attention to the wrong things.
What are we paying attention to? Do we read Scripture with a sense of urgency? Are we looking around to seeing what Jesus might be doing here and now? Is faith first on our minds and hearts?
