Name the keepers and write the code to delete all columns except the keepers.

I have a spreadsheet that people keep adding columns to. I import this sheet
and I have a macro that I hide the unwanted columns. The problem is that I
have to re-write the macro every time they add another (or change) column. I
need to write a macro that will delete the unwanted columns without
re-writing the macro.
EX:
"Column1" "Column2 "Column3"
I want to keep Column1 and Column3 and delete Column2 no matter what its
name or possition.
