For if He were on earth, He would not be a priest, since there are priests who offer the gifts according to the law; who serve the copy and shadow of the heavenly things, as Moses was divinely instructed when he was about to make the tabernacle. For He said, “See that you make all things according to the pattern shown you on the mountain.” – Hebrews 8:4-5
Hebrews 8:5 explains that the earthly tabernacle (of Moses and David) and temples (Solomon’s, Zerubbabel’s, and Herod’s) were representations of an ultimate place in Heaven which is called the “temple of the tabernacle of the testimony” in Revelation 15:5. This is the place of God’s throne, where the triune Lord dwells in fullness and rules all of creation. This is the place of the fullness of joy and pleasures forevermore (Psalm 16:11). Many wonderful details of this most glorious place are placed throughout the Bible, and it is an exciting and worthwhile journey to seek and find them. I recommend starting with Isaiah 6, Daniel 7, Ezekiel 1 & 10, and Revelation 4!
