There are few young men who cannot remember having, in their boyhood, taken a caterpillar and shut it up in a box. Before long the creature assumed a chrysalis form, and finally developed into a butterfly, with a completely new power not possessed by the caterpillar. Instead of only being able to grovel on the ground, the creature in its new existence is able to soar high into the air. This is one of Nature's conversions, and is a faint illustration of the spiritual change which takes place in the human heart, when the natural man becomes a new creature with new powers. It is customary for some to sneer at the doctrine of conversion, scorning the idea of a distinctly spiritual change taking place in the human heart. It would, however, be difficult to find any other term by which accurately to describe the change that took place in Gordon's life. [4] In this and the following chapter, I have, in order to give Gordon's views, selected quotations from his letters at different periods of his life, but not always in chronological order. For want of space a large number of extracts have had to be omitted; those that are given must be taken as specimens. Up to a certain period, while he had done well all that he was called upon to do, and had completely outstripped his peers, showing himself, in his professional capacity, to be a head and shoulders above his fellows, there were nevertheless latent powers within him, which had not yet been called into play. Who can study his life without being convinced that he had a power with God, in later life, that he did not possess earlier? Christ said, "I, if I be lifted up, will draw all men unto Me." He was lifted up before Gordon's eyes, and there was a distinctive response to the magnetic influence of the Cross; and, as in the laws of magnetism, the instrument that has been charged can in its turn charge metal brought into contact with it, so in the life of Gordon we see, that not only had the Redeemer a distinct influence on his whole nature, but that he was himself so charged with Divine love, that he was able to exert a magnetic influence over others. Ecclesiastics may fight and wrangle about names and terms; we have to deal with facts. It matters little by what name we call it, the fact remains that a distinct spiritual change came over Gordon, leaving him a man who had power with God. But though the effect of this change in Gordon's life was most marked, it is not so obvious when it took place. As a boy and a cadet he was full of animal spirits, and somewhat given to practical joking; but, though not a religious boy, he never was bad in the ordinary acceptation of the term. After he had obtained his commission, before he went out to the Crimea, there were distinct indications of a feeling after God, and some have affirmed that this was brought about through the influence of his mother. That good mothers are blessed by God as the means of conveying spiritual light to
