The priest in the holy place, directing his prayer by faith to the mercy seat, which he could not see, represents the people of God directing their prayers to Christ before the mercy seat in the heavenly sanctuary. They cannot behold their Mediator with the natural eye, but with the eye of faith they see Christ before the mercy seat and direct their prayers to Him, and with assurance claim the benefits of His mediation. (SR 155.1) MC VC

These sacred apartments had no windows to admit light. The candlestick was made of purest gold and was kept burning night and day, and gave light to both apartments. The light of the lamps upon the candlestick reflected upon the boards plated with gold, at the sides of the building, and upon the sacred furniture and upon the curtains of beautiful colors with cherubim wrought with threads of gold and silver, which appearance was glorious beyond description. No language can describe the beauty and loveliness and sacred glory which these apartments presented. The gold in the sanctuary reflected the colors of the curtains, which appeared like the different colors of the rainbow. (SR 155.2) MC VC

Only once a year could the high priest enter into the most holy place, after the most careful and solemn preparation. No mortal eye but that of the high priest could look upon the sacred grandeur of that apartment, because it was the especial dwelling place of God’s visible glory. The high priest always entered it with trembling, while the people waited his return with solemn silence. Their earnest desires were to God for His blessing. Before the mercy seat God conversed with the high priest. If he remained an unusual time in the most holy, the people were often terrified, fearing that because of their sins or some sin of the priest, the glory of the Lord had slain him. But when the sound of the tinkling of the bells upon his garments was heard, they were greatly relieved. He then came forth and blessed the people. (SR 155.3) MC VC
