The author writes with a desire to show young and old alike, that, far from being boring or uninteresting, the Old Testament tabernacle, and later the temple in Solomon’s day, is a shadowy picture of Christ and the church. It fills the believer with hope and assurance, knowing that Jesus Christ, the true tabernacle, has come to redeem his people, but there is far more to the tabernacle. Come and see.
It is true that people are perhaps easily able to draw the connections between Jesus and the sacrificial animals, as Jesus is identified as the one and only true sacrifice who takes away our sins (e.g., Heb 8-10; 1 John 2.2). But beyond the obvious connections between Jesus and the sacrificial animals, the Old Testament tabernacle is literally an entire world of references, allusions, and foreshadows of Christ and the church.
