I have been teaching the Tabernacle for years to Homeschoolers, AWANA in Churches. The message is all about the mindset to understand the Cross. Without this portion, the cross is hard to make sense of. Note too, the several ways to glean though this portion of scripture. The whole thing about how a sinner is made right before a Holy God. Redemption! Many will look at the physical items. but don't stop there. Look at how each piece points to the relevance to Christ. How about the way of worship, prayer and praise as well?
