It’s called a siesta in hot countries and in cooler ones, a nap. In those Mediterranean countries it is so hot in the middle of the day that the only sensible thing to do is to stay away from the burning glare of the sun. There is no such excuse in colder countries but a rest during the afternoon is very welcome, especially as one gets older. When I used to do public speaking the time between 2.00 pm and 3.00pm was known as the worse time to be a speaker. After a midday meal there was a tendency to nod off. (Not with my talks, of course!!)
I love enthusiasm. I think about a librarian I met recently. As her library had modernized a short while ago she was full of enthusiasm with the changes. Sadly our enthusiasm can begin to wane and projects become a burden as we get older.
Fortunately, God has no such problem, nor does He suffer from tiredness. ‘The Lord is the everlasting God, the creator of the ends of the earth. He will not grow tired or weary and His understanding no-one can follow. Is 40:28. There is no danger that God will get tired of us or give up on us because of our recurring sin. He loves us with an everlasting love.
