The truly Biblical view, on the other hand, applies atomic power and flame-throwers to the very presupposition of the natural man’s ideas with respect to himself. It does not fear to lose a point of contact by uprooting the weeds rather than by cutting them off at the very surface. It is assured of a point of contact in the fact that every man is made in the image of God and has impressed upon him the law of God. In that fact alone he may rest secure with respect to the point of contact problem. For that fact makes men always accessible to God. That fact assures us that every man, to be a man at all, must already be in contact with the truth. He is so much in contact with the truth that much of his energy is spent in the vain effort to hide this fact from himself. His efforts to hide this fact from himself are bound to be self-frustrative.
Only by thus finding the point of contact in man’s sense of deity that lies underneath his own conception of self-consciousness as ultimate can we be both true to Scripture and effective in reasoning with the natural man.
