I am not in favor calling a sin issue a disease. The medical model is a failure and is pinned on whatever language is written into whatever version of the DSM being used.
It’s a spiritual issue. So go to the Creator who created him. Church and prayer isn’t a add-on. Jesus said in Matthew 28 that “All authority in heaven and earth is given to me.” The context is global missions to spread the Gospel.
But all means all, and we learn in John chapter 1 that he has created everything.
Drug addiction is the disease to which I was referring. Addiction as a disease has been long recognized as such in the medical profession. One cannot merely decide to stop one’s “sinful choices” and behavior and no longer be an alcoholic or addict. You apparently have something about the “medical model” that has impacted your understanding to the specific issue of addiction. If that is the case, then why can’t everything in medicine be wrong? Seeing drug addiction as a disease is not an attempt to “excuse people” from sinful behavior, responsibility or bad choices. In the Gospel, people thought the blind man was blind because of his sins of his parents. Your position seems to be an analog to that.
By your answer I presume you are not familiar with AA, Al-Anon or Narc-anon. If I am wrong on this, then I really do not understand your answer. If correct, I used to be where you are. While nondenominational, the origins of AA are Christian-based, it is not restricted to Christians, but open to all. Addicts who are Christian often find God as integral to their initial and lifetime recovery. If you do nothing else, pray daily for those who are addicted, and for their loved ones who are impacted by it.
