Demographics are the most important variable in all of politics and religion. Instead of reading the Bible to find “The Truth” it would be better to read statistics about which social/economic groups are growing and which are in decline. We are all born into cultures and sub cultures. Voting patterns and church affiliation reflect what people were born into.
A book, The End of White America by Robert P. Jones carefully lays out what is happening. He heads a group called the Public Religion Research Institute. Its conclusions largely are the same as the Barna and Pew groups.
Evangelists Pat Robertson and Robert Jeffress warned that the Trump/Clinton election was the last chance to stop cultural change. Such reasoning helped Trump win the electoral election but lose the popular vote. The election did nothing to slow change. Cultural change has continued unabated since the election. Rural to urban migration has continued.
I recalled what a senior professor told me when I was a grad student during the time when racial integration was considered by some the ultimate unacceptable change. There was an election with a surprise conservative victory. “Things were just moving too fast,” the professor said. He could have been talking about today’s gay marriage and women’s equality.
That conservative victory, however, did not slow integration. Social change moved on and today no politician says schools should be racially segregated.
The percentage of white evangelicals is getting smaller. Social change, like acceptance of gay marriage and equality for women, is growing.
