The word translated as "devices" is rendered "plans" in two more recent Bible versions, but both words fail to relay the real meaning of the Hebrew word (machashebeth, for those of you interested in such things). The root word carries the idea of advice, of purpose, or imagination. A good rendering would be speculation, which is human guesswork. That, incidentally, is the source of the many false gods men have imagined down through the centuries. Having rejected, or not having access to, God's own revelation of Himself as found in the Bible, man--who is fundamentally a spiritual being--has attempted to imagine what God is like. It's interesting to note that such gods all seem to be bigger-than-life men. But God has said, "These things you have done, and I kept silent; you thought that I was altogether like you..." (Psalm 50:21). Remember this: God is nothing like us. Yes, we bear His image, vaguely and imperfectly, but for us to compare ourselves in any way to an infinite, incomprehensible God is the height of arrogance and vanity.
Now to return to the verse. As with most of the verses in Proverbs, there is a deliberate contrast. In this case, man's imaginings, his counsel, is contrasted with the "counsel of the Lord", and it is God's counsel alone that stands the test of truth. Man's counsel always comes up short.
Now let's apply that to the issue of the counsel provided by the psychological professions--including psychologists, psychotherapists, and psychiatrists--as opposed to God's counsel. (We will from this point refer to all those professions under the single banner of psychologists.) If it can be shown that the counsel provided by psychologists contradicts the counsel of God, and we accept the Biblical claim that God's counsel alone is true, then the psychological professions have very little of value to offer.
What we will be doing in the next several articles is taking a look at the individual pillars that undergird psychological theories. Although there are approximately 250 different approaches to psychology, essentially all of them rely on the same six pillars. We will be examining each of them individually, looking at their claims regarding the nature of man, and compare each of them with the Bible. Just to whet your appetite, I can tell you that every one of those pillars is at odds with a Biblical understanding of man.
