There's a War on

Join me in suffering, like a good soldier of Christ Jesus. 

No one serving as a soldier gets entangled in civilian affairs,

but rather tries to please his commanding officer.

2 Tim 2.3,4 

John Stott:

In the 2nd World War people frequently said to each other with a wry smile, "there's a war on"- a watchword sufficient to justify any austerity, self-denial or abstention from innocent activities because of the current emergency.
