The New Testament’s book of Hebrews shows the real purpose for the Old Testament’s tabernacle (and its successor the temple). That sacred tent served as a picture—“a copy and shadow”—of heavenly realities (Hebrews 8:5). Heaven, as God’s highest home, is “the true tent that the Lord set up, not man” (Hebrews 8:2). Jesus is the better High Priest who entered heaven to represent us.
We have such a High Priest, one who is seated at the right hand of the throne of the Majesty in heaven, a minister in the holy places, in the true tent that the Lord set up, not man (Hebrews 8:1-2 cf. Hebrews 9:11).
For Christ has entered, not into holy places made with hands, which are copies of the true things, but into heaven itself, now to appear in the presence of God on our behalf (Hebrews 9:24).
New worship places: spirit and truth.
Now that Jesus is our High Priest in heaven, the old tabernacle and temple are no longer needed. Having served their preparatory purpose they are now obsolete, like the Old Covenant of which they were a part (Hebrews 8:13).
While Jesus was on earth, He knew that the change of covenant was taking place. When a Samaritan woman asked about the place to worship, Jesus replied,
Woman, believe Me, the hour is coming when neither on this mountain nor in Jerusalem will you worship the Father. You worship what you do not know; we worship what we know, for salvation is from the Jews. But the hour is coming, and is now here, when the true worshipers will worship the Father in spirit and truth, for the Father is seeking such people to worship Him. God is spirit, and those who worship him must worship in spirit and truth (John 4:21-24).
