Then can your opinion be trusted? You are addicted to nicotine. Saying this addiction is wrong would convict you.
Ok...it appears that most everyone would agree that any serious addiction is a sin. Anyone disagree with this?
Some seem to believe that the seriousness (or sinfullness) of an addiction is based upon and in proportion to the harm being done to the body (the temple of the Holy Spirit).
Others believe that the seriousness (or sinfullness) of an addiction is in its master/slave relationship to fleshly desires.
Also, most seem to agree that cigarettes in and of themselves are not a sin; however they are highly addictive which makes "enjoying a smoke" an unnecessary and unwise high risk for believers who don't want to end up sinfully addicted.
I agree 100% with all I have written here and I know that I am an addicted smoker and that my addiction is not pleasing to God. We are working on it.
Even so, I also hold the view that it is important to point out ...that too often non smoking Christians combine the current world views re: the social taboos of smoking with the sinfullness of addiction to make it (in their minds) a worse offense against God than say..addictive overeating or overworking. It is not any better or any worse a sinin actuality...except in the views of the world. The result of this too common mistake is very often a self righteous attitude toward smoking and/or smokers ...which is also a sin.
