Yes, several passages in Ellen White's writings connect the concept of God's abiding presence with being a light to others. Here are a few that directly address this theme: A very direct statement on this topic says that when God's presence dwells in the heart, it is impossible to hide the light that results: > "...dwelling in the heart it is impossible to conceal the light of His presence, or for that light to grow dim. On the contrary, it will grow brighter and brighter as day by day the mists of selfishness and sin that envelop the soul are dispelled by the bright beams of the Sun of Righteousness." (PP 134.1) Another passage explains that communion with God naturally leads to sharing His love and becoming a light in the world: > "God requires His people to shine as lights in the world. It is not merely the ministers who are required to do this, but every disciple of Christ. Their conversation should be heavenly. And while they enjoy communion with God they will wish to have intercourse with their fellow men in order to express by their words and acts the love of God which animates their hearts. In this way they will be lights in the world, and the light transmitted through them will not go out or be taken away." (2T 122.2) Similarly, the experience of God's presence is described as reflecting the rays of the "Sun of Righteousness": > "Every step of faith and obedience brings the soul into closer connection with the Light of the world, in whom there 'is no darkness at all.' The bright beams of the Sun of Righteousness shine upon the servants of God, and they are to reflect His rays. As the stars tell us that there is a great light in heaven with whose glory they are made bright, so Christians are to make it manifest that there is a God on the throne of the universe whose character is worthy of praise and imitation." (GC 475.3)
