This is necessary even concerning the lawful questions of food and drink. If the children of God knew this, there would be an end of dishonour to the Lord's Name, in their bondage to 'fads' and 'fancies', and grumbles over the material things concerning the body. Alas, the 'flesh' is pandered to among God's children in a way that often spoils their testimony for Christ. Victory in this respect is also essential in the aggressive warfare against the powers of darkness, for if the believer is under bondage to a single thing-either lawful or unlawful to them as children of God they are powerless. This deals with 'habits' and desires of the physical nature of.every kind.
Smoking is surely one, and the terrible slavery to opiates and alcohol.
It is true that whilst the 'flesh' is to be crucified in an ethical sense, we do 'walk in the flesh' in a physical and lawful sense, but even 'physically' or 'lawfully', the 'flesh' is not to 'walk' over us, in any one particular. And He disarmed the Principalities and the Powers, and put them to open shame, leading them captive in the triumph of Christ. And I, if I be lifted up from the earth, will draw all men unto Me. This fact is not hidden under ambiguous language in the Word of God. Moreover, if you believe in Christ's victory over Satan, you will find more and more how essential it is that you know the Cross to crucify the old Adam-life, so that joined in spirit to the Victorious Christ, you are lifted above, and enabled to triumph over the foe, and prove that, as far as you are concerned, the prince of this world has been cast out.
