What do the materials and aspects of the tabernacle picture about Christ?

Les teaches that all the materials and all the aspects of the tabernacle are picturing Christ in some aspect of His finished work of the cross. He notes that the curtain opening into the tent used linen of white, blue, red, and purple. The tent was 45 feet long by 15 feet wide, and all the numbers in the tabernacle are divisible by 5, the number of grace. The back room, the Holy of Holies, was 15 by 15, and the front sanctuary was 30 by 15. The sanctuary had no windows and no chairs. Les asks why there were no chairs, then answers that when Christ finished His work, He sat down. Hebrews chapter 1 says that after He had finished the work, He sat down at the right hand of the Majesty on high, because His work was finished. The work of the priests, by contrast, was never done or finished.
