This is just another of MacArther's several attempts (perhaps unconsciously) to restrict what God can and should do in the name of "discernment". Take note that I am not defending the Charismatics that he is attacking. They have their shares of mistakes. But MacArther's heavily relience on reason and his so-called "Biblical Foundation" for discernment are nothing more than a subtle attempt at articulating a humanly acceptable "comfort zone", in which God "has to" operate. Anything, any phenomenon, that falls outside of this territory of human understanding are deemed "not of God". "God" in his world amounts to, if you will, a kind of complex but nevertheless abstract principle, according to which we apply our judegement on things that happen in our world, to see if they fall outside or within the boundry of the territory. This, in a nut shell, is what MacArther meant by discernment. There is no possible room for a personal God who might respond or react or interact with us. God hides behind a set of complicated algorithm that we must apply to figure out for ourselves what His wills are. Knowing God's will for MacArther means doing a meticlulous calculation on all related algorithmatical fomulas (all are of course clothed in rightous Biblical terminologies). MacArther, in all practical purposes, trusts the algorithm more than in God. One can't help but suspect that his God must contiunes to remain obscure, behind a cloud of complicated rules and formulas that are nicely termed "Biblical foundation", and that he must keep on promoting his "rules" for discernment. Becuase that is his unconscious way of proclaiming his faith in humnan reason, in his rational capability. MacArther of course cannot afford to say all this out loud. Perhaps he is not even aware of his own true motives. His own rightous words fools not only others, but also himself. This book, like many of MacArther's other books, rides on one foundamental spirit: that is, he wants to have the final say on what his world means, and through this, he controls his world.
