The Lord has given His holy commandments to be a wall of protection around His created beings, and those who will keep themselves from the defilement of appetite and passion may become partakers of the divine nature. Their perceptions will be clear. They will know how to preserve every faculty in health, so that it may be presented to God in service. The Lord can use them: for they understand the words of the great apostle: "I beseech you, therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service” (Romans 12:1) {MS 153 1899}.
