Back when I taught each of our six sons to drive I remember telling them over and over:
"Stay in your lane."
I also said "Not so close" plenty of times -- while pumping an imaginary break from the passenger seat -- but 'stay in your lane' was the instruction I repeated most.
... Which, by the way, is pretty good instruction for life too.
We're all tempted to enter someone else's space... to give advice, offer a critique or announce how something ought to be done...
... When what really matters is how well we each run our own race.
Jesus addressed this once in a conversation with His disciple Peter.
Peter asked Jesus what was going to happen with another disciple, John.
And Jesus responded by telling him to mind his own business when He said:
"What is that to you? You follow me!” (Jn.21:22).
It's far better to focus on playing your own position well than trying to manage someone else's or calling the shots as a Monday morning quarterback.
