When the horseless carriage was first introduced, there were no traffic signs or speed limits. Why do we have them now? Because of dented fenders and fatal accidents, all of which occurred because people are, by nature, selfish and unloving.
Away from the regimented life of the city, in rural areas, there are many intersections without stop signs. It is legal to go through the intersection without coming to a stop. The "law" that governs such intersections is that the person on the left must yield to the driver on the right.
Out in rural Idaho where I live, I'm amazed at how many people drive these back country gravel roads at 50 mph, going through numerous four way intersections without slowing down or looking. They assume no one is coming. One of these days, it is bound to happen though, and its going to be messy.
Within the first month of my first pastorate in a little town of 550, a County Sheriff pulled me over on downtown Main Street. Why? I had just failed to come to a complete stop at one of a few stop signs in town. I deserved a ticket, but was let off with a warning. Likely the officer knew the resulting scuttlebutt around town would be punishment enough, and it was.
Before the Law was given in writing, sin was in the world. The Law was "added because of transgressions" (Galatians 3:19) with a view to help protect lives and preserve relationships, but it was "weak through the flesh." It made nothing perfect. It is necessary, like stop signs at intersections, but results in our condemnation because it does nothing to change our selfish nature.
At various times in life, all the Christians I know roll through one of God's stop signs on occasion. It would be better to come to a full stop. It would save us some embarrassment. Yet above all, our aim is not the keeping of a written law, but to be abide in Christ and be adorned with the fruit of the Spirit, "against such there is no law" (Galatians 5:22-23).
If everyone lived in the fullness of the love of God, every stop sign and speed limit sign could be removed. What a world that would be!
