Considering that to be healed the desert bound Egyptian Israelite convoy needed to look upon the brazen serpent, and many wouldn't, it occurs to me that the ordinance of the Sacrament is analogous. It is a simple thing for many of us in the world to go to the alter, to partake and in essence look to the Savior. It does have the affect of healing, or in other words relief the the soul yoked with the effects of sin. It does require faith to approach the Savior in this way, to partake of a sacrament, perform something that may seem obscure or mysterious, but in both cases, a serpent or bread and water. It is an exercise of faith, but with the promise that [He] will pour [his] Spirit upon [you]. He does not dwell in unholy temples so this must lead us to hold to the belief that he provides forgiveness, a remission from the effects of sin, relief. There is something greater though, He promises that not only will we find respite, but that there is no permanence from the effects of sin.
