For some Christians, the prospect of broad or far-reaching psychic change raises so many and such fearful questions and concerns that it remains a step untaken, which is a pity. But for those who--while acknowledging that modern psychology may have a different anthropology or moral philosophy than Christianity does--nonetheless can see their way towards benefiting from what is good in modern psychology, then they open themselves up to a lot of potential healing, which can only be regarded as a God-given gift.
Modern psychology has of course developed greatly since Freud's death in London in 1939, with new schools and "techniques" developing since the 1950s, leading many people, from the 1960s until quite recently, ready to proclaim the death of psychoanalysis. But I find it fascinating how there seems to be increasing evidence of the efficacy of psychoanalysis over more modern forms of therapy, as noted in this fascinating article. As the author notes--rightly, in my view--the chief advantage and long-term benefit of psychoanalysis is that it "may restructure the personality in a lasting way, rather than simply helping people manage their moods."
