Of course, individuals change. I personally know too many people who have changed their lives for the better, to believe that people don't or can't change. I talking about people in general--the human race. People are people.
This morning's reading from Ephesians made me think of the present times. Paul is scolding the Ephesians:
...you must no longer live as the pagans do--their minds empty, their understanding darkened. They are estranged from a life in God because of their ignorance and their resistance; without remorse they have abandoned themselves to lust and the indulgence of every sort of lewd conduct.
Doesn't this passage sound like the people of today?
