I'd say a good metaphorical object would be potting clay, as I have a potter who hopes to make me great with His own, perfect intention, structuring me with uniqueness in His own will, and so I am cherished by Him as a valued object of His creation, alongside all of His other clay vessels, all of whom have also, alongside myself, been cast in the kiln of scorching struggle to refine and harden our ceramic edges to the will of His purpose; His ultimate intention for all of us that lacks all flaw because He is our maker, that who knows His creation best, and who sculpts our souls to carry His water, which is His guiding spirit.
