We spend a lot of time being concerned and ruminating in our minds people, places and things that are in the past, and our choices that we can't control.
Here is something that should bring us comfort. The Creator of the universe plays several roles in our lives, whether we know it or not like the following:
Provision, so we don't lose sleep over what we can and can't do;
Victory over our past, present and future and;
Peace in the midst of every adversity we face.
Take a deep breathe, lay your head down, and drift off to sleep, knowing that all is well.
