There is only one entrance into the Tabernacle.
John 14:6 "I am the Way, the Truth and the Life. No man comes to the Father except through me." Jesus is the only way to God.
The purpose of the tabernacle was for God to dwell among his people.
John 1:14- The word became flesh and DWELT among us."
Emmanuel- God with us. This is Christmas.
The alter of incense not only illustrated Jesus' role as intercessor but we noted one of the wiseman's gifts as well.
The table of bread in the tabernacle- we read that Jesus calls himself the Bread of Life in John 6:35. We also loved the connection to Jesus being born in Bethlehem (of "House of Bread")
The lamp stand- John 8:12 Jesus calls himself the Light of the World. We also noted the angles and the star were lights that pointed to Jesus too.
The ark of the covenant held the stone tablets- or God's words.
The manger held the Word of God- Jesus. John 1:14- "the Word became flesh and 'tabernacled' among us."
We also had the opportunity to be in Lancaster, PA over Christmas break and there is a life-sized Tabernacle there to tour through. 
A sweet Advent this year.
