First, the tabernacle is a symbol of the body or soul of a person. There are three stages.
Stage One: The Courtyard: Passover and Feasts of Unleavened Bread: Spring -New Creation
This stage a priest makes a sacrifice, cleanses his body, and puts on priestly garments.
Physical meaning: The sacrifice is a lamb, the cleansing is the Red Sea,
Spiritual meaning: The sacrifice is Jesus, the cleansing is baptism, the garments are righteousness
Stage Two: The Holy Place: Pentecost: Summer -Sanctification
Physical meaning: table of shewbread, candlestick, incense
Spritual meaning: fellowship, light (holy spirit by reading the bible), prayers. (These are actions of service which each Jew and Christian can perform)
Stage Three: The Most Holy Place: Feast of Tabernacles: Fall -Final Redemption
Physical Meaning: Law - manna - Aron's Staff
Spiritual Meaning: Holy Spirit - Jesus's body - Priestly authority and leadership
It also took one full year from the time Moses held the passover until the completion of the sanctuary. Likewise, there are many devotionals such as "The bible in a year". Symbolically we create the tabernacle within us each and every year.
