For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ. – 2 Corinthians 4:6

In and around the tent wherein the Lord dwelt in the center of the camp there was a manifestation of the presence of God. This was the glory of that house: but how scanty was the revelation! A bright light, the Shekinah, is said to have shone over the mercy-seat; but the high priest only could see it, and he only saw it once in the year when he entered with blood within the veil. Outside, above the holy place, there was the manifest glory of the pillar of cloud by day, and of fire by night. This sufficed to bear witness that God was there; but still, cloud and fire are but physical appearances, and cannot convey a true appearance of God, who is a spirit. God cannot be perceived by the senses; and yet the fiery, cloudy pillar could appeal to the eyes only. The excellence of the indwelling of God in Christ is this-that there is in Him a glory as of the only begotten of the Father, the moral and spiritual glory of Godhead. This is to be seen, but not with the eyes; this is to be perceived, but not by the carnal senses: this is seen, and heard, and known, by spiritual men, whose mental perceptions are keener than those of sight and hearing. In the person of the Lord there is a glory which is seen by our faith, which is discerned of our renewed spirits, and is made to operate upon our hearts. The glory of God in the sanctuary was seen only by the priest of the house of Aaron; the glory of God in the face of Christ is seen by all believers, who are all priests unto God. That glory the priest beheld but once in the year; but we steadily behold that glory at all times and are transformed by the sight. The glory of God in the face of Jesus Christ is not a thing of outward appearance, to be beheld with the eyes, like the pillar of cloud and fire; but there is an abiding, steady luster of holy, gracious, truthful character about our Lord Jesus Christ, which is best seen by those who by reason of sanctification are made fit to discern it. Blessed are the pure in heart, for they shall see God; yea, they do see Him in Christ Jesus. ~ C.H. Spurgeon
