Romans 8:5 For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. 6 For to be carnally minded is death; but to be spiritually minded is life and peace.
The way for us to keep temptations on appetite at bay, in all of their varied forms, and the way for the cravings and desires of the flesh not to faze us, is by having Christ formed within, for He alone is able to keep us from falling. A common mistake that is made, even by many Christians is to try and tackle the issues of diets and food, and any other craving for that matter, on our own because they are issues in the temporal realm.
Again, there are persons who have fallen into the snare of becoming promise keepers, who believe that by strict self-denial, and sheer will power, they will be able to resist the clamors from within and without.
But while it is true that firm decision-making is an integral part of overcoming, our decision to do the right thing does not guarantee that persons always would. Decisions must be coupled together with the supernatural power of the Holy Ghost to give us the momentum, and staying power to resist the fierce urges of the flesh.
Romans 8:7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be. 8 So then they that are in the flesh cannot please God. 9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
May The Lord add His blessing to the study of His word. God bless!
