Our Body is a Temple of God
We are like a temple of God due to our soul dwelling within and attached via a silver chord. We have a duty to exercise the body keep it well maintained in order to utilize it for life’s mission. Without our human body, Gods plan to experience the everything could not unfold. Hence the longer the body lasts, the more progress we can make and the more we can glorify the universal plan. As a temple of God, God has made the body with everything needed to sustain and heal itself, including the ability to absorb nutrition from different sources.
Not just food and exercise, what in put into our minds and the environment also control how we practice spiritually. In a negative environment it is very difficult to believe in non tangible esoteric concepts. Not because they are difficult to grasp, but because so many people want to pull us down.
