from John Owen, Meditations and Discourses on the Glory of Christ:

There are three ways whereby the glory of Christ is represented unto us in the Scripture:

First, By direct descriptions of his glorious person and incarnation. Secondly, By prophecies, promises, and express instructions concerning him, all leading unto the contemplation of his glory, which are innumerable. Thirdly, By the sacred institutions of divine worship under the Old Testament: for the end of them all was to represent unto the church the glory of Christ in the discharge of his office; as we shall see afterward.

We may take notice of an instance in one kind under the Old Testament, and of one and another under the New.

His personal appearances under the Old Testament carried in them a demonstration of his glory. Such was that in the vision which Isaiah had, "when he saw his glory, and spake of him," "I saw the Lord sitting upon a throne, high and lifted up, and his train filled the temple. Above it stood the seraphim," etc. It was a representation of the glory of the divine presence of Christ filling his human nature, the temple of his body, with a train of all-glorious graces. And if this typical representation of it was so glorious, as that the seraphim were not able steadfastly to behold it, but "covered their faces" upon its appearance, how exceeding glorious is it in itself, as it is openly revealed in the Gospel!
