Quote from A Course in Miracles Text Chapter 21 - REASON AND PERCEPTION.

T-21.III.11. Think you the Holy Spirit is concerned with this? 2 He gives not what it is His purpose to lead you from. 3 You think He would deprive you for your good. 4 But "good" and "deprivation" are opposites, and cannot meaningfully join in any way. 5 It is like saying that the moon and sun are one because they come with night and day, and so they must be joined. 6 Yet sight of one is but the sign the other has disappeared from sight. 7 Nor is it possible that what gives light be one with what depends on darkness to be seen. 8 Neither demands the sacrifice of the other. 9 Yet on the absence of the other does each depend.
