|A modern march of the Ark of the Covenant.|
It gives us some perspective.
Of course, this is a different ark than Noah built in Genesis. For those whose exposure to the Ark consists of the Indiana Jones movie, we see here that it was the original understanding of how God communicated with the people.
Rather than a construction that is stationary like the Temple (built years later when they had settled), this would be on the move with the people wherever they went.
The ark of the covenant gives an image of God that is similar to the missional movement within the church that states that Christians are to get outside our walls and impact the community. It meets people where they are.
If you were to imagine God meeting you where you are - in all of your triumphs and failures, what would that look like? What does that say about God? What does that say about us?
I may not see the need for all of the finery of the ark, but I like what it represents. God is not someone waiting for us to visit. God comes to us!
