I'm not a religious person.
Last I recall from the stories, there were two other people crucified with Christ.
One took, responsibility for his actions, said he was sorry and he was saved.
The other, remained a criminal, denied responsibility for his actions and was not saved.
What's my point? Our alcoholics could be a parallel to the guy who denied his role. It wasn't up to Jesus to make him believe. We/me need to be more like the guy who took responsibility for their actions/life and was rewarded.
There's nothing wrong with helping people and I don't see help as codependent behavior.
