Here is the hidden (invisible) perspective of the natural (visible) account of the ark.
The ark of the covenant and Noah’s ark are the same thing. Both were sealed/overlayed on the inside and the outside. The ark represents the image in the lookinglass when we build them according to spec. In other words, man needs to be made into the image of God over time. It starts with the Holy Spirit in us given the instructions for the building up of the Son thru us, and finishes with us abiding in the Holy Spirit. We are overlaid (covered) in the spirit from the inside out.
