When it comes to smoking, after I got saved I seem to have lost all desire for smoking because I was no longer drinking alcohol and coffee anymore but I began to have one cigarette once a week at a friend's place and one night on my way there I heard the audible voice of the Lord saying he did not want me to smoke but I had a cigarette that night and halfway through that cigarette I got so sick I was in my friend's bathroom for 2 hours and I never had a cigarette again and that's 31 years ago yet I had smoked for 16 years before I was born again. Because of the way the soul works you can have Holiness working in certain areas of your life yet have unholiness working in other areas, my recommendation is to do a deep study of what the word says about who and what you are in Christ and begin to meditate those verses as much as you can every day because the word of God has been given to us in seed form which is what The Parables of the sower are all about and as you keep meditating and coming in agreement with what the word says about who and what you are in Christ those words will begin to grow on the inside of you in your soul and eventually you will lose all desire for smoking and many other things will come out of this and this is all part of sanctification or even discipleship, it's part of the process of growing from a child of God into a son of God called sonship, and this my brother is part of putting off the old man and putting on the New Man who happens to be Christ. Hope that helps.
