Any course of action that weakens your physical or mental power unfits you for the service of your Creator. We are to love God with all our hearts, and if we have an eye single to His glory we shall eat, drink, and clothe ourselves with reference to His divine will. Every one who has a realizing sense of what it means to be a Christian will purify himself from everything that weakens and defiles. All the habits of his life will be brought into harmony with the requirements of the Word of truth, and he will not only believe, but will work out his own salvation with fear and trembling, while submitting to the molding of the Holy Spirit. (TMK 115.5) MC VC
