“While Moses was in the mount, God presented to him, not only the tables of the law, but also the plan of salvation. He saw that the sacrifice of Christ was pre-figured by all the types and symbols of the Jewish age; and it was the heavenly light streaming from Calvary, no less than the glory of the law of God, that shed such a radiance upon the face of Moses. That divine illumination symbolized the glory of the dispensation of which Moses was the visible mediator, a representative of the one true Intercessor.
The glory reflected in the countenance of Moses illustrates the blessings to be received by God’s commandment-keeping people through the mediation of Christ. It testifies that the closer our communion with God, and the clearer our knowledge of His requirements, the more fully shall we be conformed to the divine image, and the more readily do we become partakers of the divine nature.”
