Bottom line, you can't control another living soul. I mean, I guess some of you can if you are abusive, control the money, the car, the resources, etc. But if you don't, you can plead with people, hold scripture up to their faces, give them example after example of the truth, involve others and people will still do what they want to do.
So what do we do then? You help those who seem to really want help because they have made some changes already. You pray for the others. Extend grace to everyone else. And then realize, you do the same thing too to everyone else.
