Drew, I cannot believe you continue to raise this flag and compare smoking to having an adulterous affair. Apples and oranges!! If you're going to use a comparator, you're going to have reach for new material. This doesn't hold water. Try comparing smoking to something that is clearly forbidden in the Word such as adultery doesn't work. You can't keep marching out adultery and asking if it's okay to do this as well.
My usual disclaimer... never smoked, don't smoke, never will smoke.
I do believe there can be the argument that if a person is relying on anything to calm their nerves and not trusting in the Comforter to quell their anxiety, there can be a disconnect there, and they need to be in prayer about why they are smoking. I do believe smoking is very unhealthy, which is one of the reasons I don't do it.
But whether in the form of a pipe, a cigar or a cigarette, I believe it's a stretch to say smoking in and of itself (aside from personal idolatry/dependence) is necessarily a sin. There's typically no physical benefit to popping a square of sugar in your mouth. I don't know much about diabetes, but this might be an exception. It would be dead caloric intake without any benefit and have negative consequences. Is eating pure sugar a sin?
I'm fine with someone stating that they believe smoking is a sin. But to say it's not up for debate and to call smokers sinners is taking it too far.
James 3
"<sup class="versenum" id="en-NIV-30337">17</sup> But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere. <sup class="versenum" id="en-NIV-30338">18</sup>Peacemakers who sow in peace reap a harvest of righteousness."
James 4
" <sup class="versenum" id="en-NIV-30349">11</sup> Brothers and sisters, do not slander one another. Anyone who speaks against a brother or sister or judges them speaks against the law and judges it. When you judge the law, you are not keeping it, but sitting in judgment on it. <sup class="versenum" id="en-NIV-30350">12</sup> There is only one Lawgiver and Judge, the one who is able to save and destroy. But you—who are you to judge your neighbor?"
Now, I do believe scripture speaks to righteous judgment. We do no favors to our brothers and sisters by ignoring blatant sin while admitting our own shortcomings. But since there is no direct scriptural forbidding of smoking, I believe this can cause more divisiveness than good within the Body of Christ. There's little building up and more tearing down.
