There is an old trucker phrase I remember from my CB days, "keep it between the ditches."
That phrase morphed into "keep it between the lines"
as ditches disappeared from along mainroads. But, the phrase carried the meaning into basic, everyday life by equating to our life journey along the 'highway of life'. As we travel, we need to keep it between the lines. To wander to the left or to the right means trouble. We may go off the road and into the wilderness. We may end up in a ditch, stuck. Or, we may collide with another in life, going the otherway, if we cross over the center line.
The author of Proverbs takes this same idea in chapter 4, applying it to real life. Look down at 23 thru 27. See it? We'll spend time there, noting an outline form and how those verses apply to our lives.
So, as you journey, I encourage you to keep it between the lines! Christ's Peace to you.'
