Blue

Yes the sky really is blue on a day like today.
Some years ago I went to the Tate Modern, not my favourite place - I may be a philistine, but it seems a bit of a con. For example there was (maybe still is) a square of shiny blue perspex on the wall, maybe a foot by a foot called "blue". I remember thinking someone has probably
received some huge sum of money for that.
Our Creator does not need perspex. The heavens declare the glory of God.
