But stop and think a minute. It is both foolish and futile to demand that either the =implements= or the =faculties= used in the scientific realm shall be brought over and used in the pursuit of spiritual truth. This is precisely the thing we are seeking to show. But that does not mean for a moment that the inquirer must therefore give up the =scientific attitude of mind= and cease to work according to the demands of the =scientific spirit= the moment he begins inquiry in the spiritual realm. For that spirit is simply an honest and accurate method of investigation, and because science is compelled to stop at the border of the spiritual realm is no reason why we should cease being honest and accurate when we investigate in that realm. It is perfectly true that the scientist, as such, has absolutely no pronouncement to make concerning spiritual truth; but it is equally true that the inquirer in the spiritual realm, if he does not pursue his inquiries by scientific methods and according to the demands of the scientific spirit, will have no pronouncement to make either. The man who intends, therefore, to be scientific enough in his spirit to give primary truth its place of primacy by interpreting in its light the truths of other realms, and who, with the instincts of the true scientist, recognizes spiritual truth as primary in its relation to the natural, will be actuated sufficiently by his scientific attitude to determine to know what spiritual truth is, in order that he may be able to interpret natural truth in its light. This will bring him face to face with Christ's formula for entering upon the knowledge of spiritual truth. Being honestly desirous of knowing what spiritual truth is, he will determine to do God's will in order that he may find out. =a.= This Will Mean Surrendering the Heart to God. This is the only thing it can mean. For spiritual truth is primarily heart truth, not intellectual truth, and the only way to know heart truth is to surrender the heart to that Holy Spirit of truth who "searcheth the deep things of God," and who was sent into the world to "lead us into all the truth." The grammarian, the philologist, the historian, the naturalist, the philosopher, therefore, have no service they can perform here. They cannot carry their apparatus over into the spiritual realm and weigh and measure, estimate and judge, illumine and interpret spiritual truth for us. When we stand here we are on that holy ground where we must lay off our sandals of scientific paraphernalia and stand before God with open heart ready to hear what He has to say. The moment we get to this realm, the whole apparatus by which truth is received changes from reason to faith. But do you see where this brings us? Straight back to Christ's formula! This is precisely what His formula involves, for when a man wills to do God's will, he takes the first step in faith.
