If I ever see this street sign when I am driving my vehicle, I do not intentionally drive down the road that way. But I confess that during my life I have been stubborn, determined, and foolish enough to make choices that took me down a path that was clearly marked Do Not Enter!
I suspect you remember doing something like that too. I hope you can remember both the times when you clearly chose the better path and the times when you blew it because both are important to keep in mind. When I see someone heading down a path that isn’t good, I definitely pray for them. If I am in a position to chat with them, I consider doing that too. But what I really want to do is jump up and down and say “Don’t do it!” Sometimes my concern comes from personal experience — I traveled down a similar path and endured some difficult consequences. Other times my age and life experience can help me see when something might not turn out well.
Where did I get that experience? From making poor decisions and learning where those decisions can lead. There are times lessons can be learned vicariously but there is a certain segment of the population that feels the need to throw caution to the wind and forge their own difficult path. Pray for them as you see them traveling. God can redeem difficult situations and circumstances. He has done it for me and He can do it for you.
