Except that I don't confuse the two. What I understand by individual happiness is that the individual comes first with themselves. We see this in the context of such things as the Panama Papers, where the individual is primary whilst society is relegated to the back burner or even further than that. Such people still adopt sets of personal boundaries and fel perfectly OK with how they treat others.
Unfortunately, in such cases each individual set those boundaries for themselves - and they sometimes feel that they aren't obliged to respect the boundaries that society has set around itself.
They believe that they do, and they have every right to do so, but it can be asked whether they really do experience the full extent of happiness that they - as humans - can experience.
Oh for goodness' sake, Hope! So no Christians go for tax avoidance schemes?
And why are society's boundaries superior to any that I might have? It wasn't so long ago that society said that single parenthood was shameful, that gay relationships were criminal, that a man couldn't rape his wife. Thank goodness people have seen fit to challenge society over those boundaries.
Hard though it may be for you to accept, I'm happier since deciding that Jesus doesn't want me for a sunbeam. Not least because I had to come out of my smug little Christian bubble and see the person it had made me into - not one I feel proud of being, if I'm honest. I don't know if I'm a better one now but I think I'm probably nicer to be around.
