All cars flow down the same mainstream of the expressway,
And meet for a while, traveling the same road.
They ride side by side touching for a brief span of time, being under one  fellowship.

Then the expressway divides and fellow travelers go their own ways, never having met but yet together.
They divide never to see each other again or meet and yet they have touched each others' lives.

And also they were once under one divine hand with the same pre-determined destination.
Now they part and go different ways, yet they are still protected by one hand.
