Vitamin D
In the October 2021 General Conference, Elder Uchtdorf said, "We need an ongoing, daily infusion of heavenly light." Vitamin D is a compound that the body synthesizes in the skin from daily exposure to sunlight. Vitamin D is necessary to various vital bodily functions. I believe that a similar process happens with our spirits. When we allow heaven's light to infuse our spirits, our spirits are able to synthesize faith, hope and charity. Just like sunlight helps the body create compounds vital for its survival, God's light helps the Spirit create compounds vital for its survival - peace, joy, humility, patience, strength. We need this daily infusion of Heaven's light because like oil in a lamp, our faith and hope and love are resources that get used up throughout the day. But if we take in the light of the gospel each day, our spirits can create more faith, more hope, more love, each and every day that we flood our souls with the light of Christ.
