Quote from A Course in Miracles Text Chapter 5 - HEALING AND WHOLENESS.

T-5.II.4. You are the Kingdom of Heaven, but you have let the belief in darkness enter your mind and so you need a new light. 2 The Holy Spirit is the radiance that you must let banish the idea of darkness. 3 His is the glory before which dissociation falls away, and the Kingdom of Heaven breaks through into its own. 4 Before the separation you did not need guidance. 5 You knew as you will know again, but as you do not know now.
