Biologically speaking, the change of a caterpillar into a butterfly is spoken of as a “metamorphosis.” The ugly, repulsive caterpillar is confined to a tomb which it spins for itself. While in the cocoon there is an apparently dead and formless substance. But after the warm sun of spring has beaten its golden rays upon that cocoon, there comes forth a beautiful butterfly. Though the butterfly is different in appearance from the caterpillar, we recognize the beautiful winged insect as being the same as the caterpillar. It is the same living creature, yet different. So also is the resurrection of the body. Now we have a vile body (or a body of humiliation). The Apostle James calls it a “low” body, “because as the flower of the grass he shall pass away” (James 1:10). The body of Adam, in its original state, was provided with a covering of glory, but when sin entered the covering of glory was replaced with a covering of humiliation. In our present bodies of humiliation we are unfit for the glories of Heaven and God’s presence, but hopefully we look for our Lord’s return when He shall fashion our bodies of humiliation like unto His own body of glory. It will be the same body in that it will be recognizable, but wonderfully changed.
The idea that caught my attention in this paragraph is the “covering of glory” which Adam had in his original state. I don’t know if this is particularly scriptural, as it isn’t cited, and whether that covering was a physical or a mental state. I tend towards the mental. Adam and Eve, such as they were, had perfect bodies, naturally glorious. Then one of the effects of their sin was that they were no longer covered by glory, but were instead covered by humiliation. That’s an interesting concept to swirl around.
