The traditional method had explicitly built into it the right and ability of the natural man, apart from the work of the Spirit of God, to be the judge of the claim of the authoritative Word of God. It is man who, by means of his self-established intellectual tools, puts his “stamp of approval” on the Word of God and then, only after that grand act, does he listen to it. God’s Word must first pass man’s tests of good and evil, truth and falsity. But once you tell a non-Christian this, why should he be worried by anything else that you say. You have already told him he is quite all right just the way he is! Then the Scripture is not correct when it talks of “darkened minds,” “wilful ignorance,” “dead men,” and “blind people!” With this method the correctness of the natural man’s problematics is endorsed. That is all he needs to reject the Christian faith.
