Thine eyes did see my substance, yet being unperfect. While as yet the vessel was upon the wheel the Potter saw it all. The Lord knows not only our shape, but our substance: this is substantial knowledge indeed. The Lord's observation of us is intent and intentional, —"Thine eyes did see." Moreover, the divine mind discerns all things as clearly and certainly as men perceive by actual eye sight. His is not hearsay acquaintance, but the knowledge which comes of sight. And in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them. An architect draws his plans, and makes out his specifications; even so did the great Maker of our frame write down all our members in the book of his purposes. That we have eyes, and ears, and hands, and feet, is all due to the wise and gracious purpose of heaven: it was so ordered in the secret decree by which all things are as they are. God's purposes concern our limbs and faculties. Their form, and shape, and everything about them were appointed of God long before they had any existence. God saw us when we could not be seen, and he wrote about us when there was nothing of us to write about. When as yet there were none of our members in existence, all those members were before the eye of God in the sketch book of his foreknowledge and predestination.
This verse is an exceedingly difficult one to translate, but we do not think that any of the proposed amendments are better than the rendering afforded us by the Authorized Version. The large number of words in italics will warn the English reader that the sense is hard to come at, and difficult to express, and that it would be unwise to found any doctrine upon the English words; happily there is no temptation to do so. The great truth expressed in these lines has by many been referred to the formation of the mystical body of our Lord Jesus. Of course, what is true of man, as man, is emphatically true of Him who is the representative man. The great Lord knows who belong to Christ; his eye perceives the chosen members who shall yet be made one with the living person of the mystical Christ. Those of the elect who are as yet unborn, or unrenewed, are nevertheless written in the Lord's book. As the form of Eve grew up in silence and secrecy under the fashioning hand of the Maker, so at this hour is the Bride being fashioned for the Lord Jesus; or, to change the figure, —a body is being prepared in which the life and glory of the indwelling Lord shall for ever be displayed. The Lord knoweth them that are his: he has a specially familiar acquaintance with the members of the body of Christ; he sees their substance, unperfect though they be.
