The Old prophesied the New and the New is fulfilling the Old.

The map in the background is the area where the tabernacle traveled with the Israelites.
The purple color represents royalty of Jesus who is the King of kings and the Lord of lords. The scroll that contains the actual Hebrew writing of the Book of Leviticus.
The golden box in the front is the incense altar that is located in front of the Most Holy Place inside the tabernacle. It is a cubit long and a cubit wide, and two cubits high, made of acacia wood which represents humanity in the Bible. Acacia wood does not rot. It means a Man without a sin, Jesus. The altar is laid with pure gold which represents divinity.
Instead of putting incense on this altar, the designer took liberty to put the Perfect Lamb of God which is sweet aroma to God's nostrils.
The Lamb sitting on the incense altar is casting a shadow of Cross to the scroll of Leviticus.

Jesus is our Atoning Sacrifice for our sins.
