If our eye or mind or soul is single to the glory of God; if our desires, our ambitions, our hopes and dreams are centered in the things of righteousness; if our greatest reason for serving is to build up the kingdom of God and establish in the earth the righteousness of God-if we are thus centered, then we will be spiritually transparent, the light of the Spirit of Almighty God will shine through us and we shall be a light to the world.
If our will is subject to the will of heaven, then there is in us no hindrance to the power and glory, the light, of the Father; others will see him in our countenances. Those who have and maintain an eye single to the glory of God are on that path which allows them now to see and understand things that are mysterious to the worldly and that will lead them, in the Lord’s due time, to that highest of spiritual rewards-the privilege of seeing him face to face.
“And if your eye be single to my glory,” the Savior declared in 1832, “your whole bodies shall be filled with light, and there shall be no darkness in you; and that body which is filled with light comprehendeth all things. Therefore, sanctify yourselves that your minds become single to God and the days will come that you shall see him; for he will unveil his face unto you, and it shall be in his own time, and in his own way, and according to his own will.” (D&C 88:67-68.)
