Mixed Motives and Methadone

I just read a blog from an atheist who took exception with street preachers who hung out in the pub district and offered aid to the revelers there.  He made some great points.  One of his problems with these folks was that they did good out of mixed motives.  They offered physical assistance to people in crisis but they also wanted to spread the gospel.  So my question is, “What’s wrong with that?”

Consider a non-profit organization whose goal is to help heroine addicts.  They open a methadone clinic hoping to attract addicts seeking relief from withdrawals.  At the clinic they also offer rehab services.  Should we fault them for having mixed motives?

As believers in Christ, we believe that humanity suffers from one problem, sin.  That disease manifests itself through a myriad of symptoms.  Whether we’re addressing symptoms or offering a cure the mission and the motive remain the same.
