So it is not just matter conscience to you, but also of law, as you said before.
I feel that it is a sin, based on principle not on law.
The real point here is your duplicity.
Neither smoking, nor drinking, nor money, nor sex, nor drugs, nor caffeine, nor food, nor anything made in the world by man through the intelligence of Christ is unclean and sinful transgression of the law of Christ.
Lust abusing any such thing makes them sin and unclean.
The only time they are sin themselves for a particular individual, is when the personal conscience is weak towards it, and so the weak individual makes a zero-tolerance policy for himself.
Which is perfectly fine, but then to go on and judge others by their own forbidding fruit, is to become a lawmaker and false judge over others' liberty.
If you're not going to be honest with yourself about what you are doing, then there is no reasonable case to be made.
I.e. I have absolutely no problem judging anyone as a sinner and false witness of Christ by fornication, because I can easily quote several Scriptures plainly saying it is transgression of Christ's law.
You have no Scripture to quote, but only your own weak conscience and mind of false judgment upon others.
I bear witness of Christ according to Scriptures. You bear witness of yourself.
Many of them did however, but out of love for Him and neighbor, have successfully quit.
I don't smoke at this time, but if I did, then I would not do so before someone truly weak of conscience about it.
But since you are a lawmaker, trying to make his weak conscience into some sort of strength of faith, I would gladly light up in front of you. In fact, if I knew I was around such as you, I would light up whether I really wanted to smoke or not, just to put your lawmaking pride in its place by my liberty in the Lord.
Nothing personal. I have just learned the hard way to reject out of hand false lawmakers and judges.
Actually Rob it is a law to Jehovah's people. Although it is based upon principle, the governing body of Jehovah's witnesses has determined that those who choose to smoke cannot be a part of our faith. So one has to decide if they are in fact the faithful slave that Jesus assigned to shepherd his sheep until his return or not. Do you think the Bible identifies the faith beyond reasonable doubt?
