"For God who said, 'Let light shine out of darkness,' made His light shine in our hearts.... But we have this treasure in jars of clay, to show that this all-surpassing power is from God and not from us." (2Cor 4:6-7)
A jar of clay? A pot. An image of earthly humanity. And at my age, my "pot" has been used and beat around. Which makes me what? A cracked old pot, not so much containing God's glory as helplessly hoping that's what will shine through and ooze out in a way that blesses my world.
