"…(A)postasy from truth in areas of doctrine also brings with it loss of interpretive soundness. There is a correlation between obedience to what the Most High has taught in the Bible and the Holy Spirit's guidance of people's understanding…Doctrinal apostasy offends the Comforter, so that he will no longer guide the student of the Bible into all truth, according to the Savior's promise (Jn. 16:13). For studying prophecy, a special preserve of the Holy Spirit, the result cannot fail to be intellectual confusion." (Edwin de Kock, The Use and Abuse of Prophecy, 7,13)
