Jeremiah 8:20: The harvest is past, the summer is ended, and we are not saved.(I have linked to The Message, and quoted from The Authorised Version.)
Here in the UK, we are definitely sensing that the summer is over. There is a chill in the air, leaves are changing colour. Soon, we'll be getting up in darkness, eventually getting home from work in darkness. The verse doesn't bite the way it used to. Then I was lamenting my singleness; now I have a family - that makes a huge difference. Life is difficult, but I don't feel, as I did then, that it lacks purpose.
There, I started with a doleful verse, and I seem to have cheered myself up!
