Even a peep hole will have to do!
Often we cry when a door is closed to us especially if it is something we loved and treasured. This is only a natural reaction because the hows and whys are not visible to us. Sometimes it is the job we loved doing and then suddenly due to circumstances beyond us we are forced to walk away. It may even be a relationship that we invested everything into, the kind we know you lost the other part of your soul. You know you did everything by the book, you loved, you cared and you worked hard on it. We sit and over-analyse were it all went wrong and still we cannot pinpoint an exact element that made it all go so wrong.
However if you look back at those things years later you realise nothing happens for no reason. Maybe the person you thought was your soul-mate dies and you suddenly think I could have been a widow by now but God did not allow it. You still love and miss the person but it just was not your destiny to end up all alone. Or maybe that job you cared about turns out it went down under quicker than anyone ever imagined and you came out unscathed because God moved you just in time.
The trick in life is that if a door has been shut whether by Gods design or other ungodly unforeseen entity, you better be smart to start looking for an open window, if there is no open window, an air vent will have to do otherwise in the worst case scenario even a peep hole can be dug to provide a means of escape. You just have to find a way out. A closed door is not the end of your life it is just the start to an ingenious mind and achieving greater things.
