There is one church which doesn't have a need to lock their doors. The Church of Perpetual Adoration. They pray in shifts 24/7/365.
You keep your front door open for 24 hours a day then and see how much property you have left in your home after a couple of days! They have to close and lock their doors, first of all churches can have valuable items in their care, no insurance will cover anyone who does not take basic security, like locking a door!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
