Our souls are the union of our bodies and our spirits (see D&C 88:15). They are integrally entwined, and one cannot thrive while the other is neglected. While each of us is given a different degree of physical health in this life, it is our Heavenly Father’s plan for all of us to work to improve what we have received. Both our bodies and our spirits must be nourished and exercised to be healthy and to help us reach our full potential.
