For me, one of the striking things about the tabernacle is not the design or the foreshadowing of God's redemptive purposes, but the lengths to which God goes in order to be able to live amongst his people. It should not be possible for a holy God to be so close to an unholy people without judgement ensuing. But because of God's gracious and forgiving heart towards his people he makes it possible using tents and altars.
In other words, God does not make it too complicated for us to draw close to him, in fact he makes it as simple as possible.
Of course eventually he makes it really simple: Jesus said, "Whoever believes in me has eternal life."
