The great thing about signs - billboards ads, traffic signals, garage sale posters - is that they work hard to catch your eye with minimal effort from us. We give bonus points to signs that are clever or entertaining. So here comes Jesus talking about the sign of Jonah, "Just as Jonah became a sign to the Ninevites, so will the Son of Man be to this generation." (Luke 11:30) This sign is about repentance from sin. What's clever or catchy about that? And worse, this is the kind of sign that requires work on our parts, with no immediate reward. Still, Lent is the time to open our eyes to some of the more challenging signs Jesus wants to show us. What sins do I need to repent of during this season? This is tough work, but it needs to be done, and Jesus is here to help.
