Speaking as a former addict........ My screen name comes from the whites on my knuckles as I was gripped up on the steering wheel. I was fighting the urge to go to the liquor store about a month sober. LOL, I'm surprised i didn't rip that thing off!
For one, I was neither spoiled or selfish. I started drinking as a way of "self medicating". I truely didn't know I was an alcoholic. I held down a job, took care of business and didn't get the shakes. It was a good 5 or 6 years into drinking when I realized I was an alcoholic. Addiction is something that sneaks up on a person.
While a person is on whatever it is they're addicted to, they are selfish. That's an understatement. Often times the person addicted honestly doesn't know they're addicted, or even acting abnormal.
The Lord delivered me from all of that. About a year ago I was having problems and turned to alcohol again. My I drank every day for 3 days. Apparently the Lord wasn't going to allow me to go down that path again. It's over now.
I know that even believers can become addicts. I believe the Lord can and will deliver them too.
From my experience, addiction is a part of the flesh. The difference in a believing addict and an unbelieving addict is being able to stop. The Lord gives wisdom and strength, delivery, and recovery. That doesn't make it all easy to quit either.
I feel sorry for addicts and for the people around them. Those who are addicts are deeply hurt and deeply lonely. They honestly don't know what to do.
