After learning even just a little about what Christian Science teaches of God’s, divine Spirit’s, reality and all-presence, one’s thoughts might naturally overflow with profound happiness. What heartening, wonderful news: Spirit and its manifestation, which is wholly good, actually makes up the entirety of existence! As one then continues to investigate Spirit’s utter all-presence and nature and, more importantly, begins to integrate this spiritual understanding into daily life through experiences of healing, one can’t help but feel prompted to deeply examine the corollary that Spirit’s opposite, matter, must be an illusion.
