When I grew up, the rainbow was a reminder of God's promise never to flood the entire Earth again and the word "Gay" meant happy.  The Covid virus, which originated in China demonstrates how society changes. Call the Spanish Flu by it's name and it isn't racist. Hong Kong Flu? Not racist. China Virus? Racist.  Next we're going to change the rules that discriminate against birds and swine.

Society continually changes but God set an unmoving standard for us. His rules never change. His promises to Abraham apply as much today to believers as they did when God spoke them to Abraham.  To help understand this, think of the difference between Truth and Fact. Facts change. If you don't believe that, look at your driver's licence photo from 10 years ago and you'll see that the facts about your appearance have changed. Truth never changes. It is wrong to murder someone today, just as it was when Jesus walked the planet. Truth never changes.
