Earthen vessel

"But we hold this treasure in earthen vessels, that the surpassing power may be of God and not from us."  (2 Corinthians 4: 7)

Earthen vessels, vessels of clay, weak morality, inconstancy, concupiscence, sinful nature; these are  synonyms for earthen vessel described  by St. Paul in 2 Corinthians 4: 7.

How about "this treasure"?
Genuine riches, Holy Spirit, Faith, Christ in us the hope of glory, the Sacraments are some of the treasures of redemption.

I don't feel confident in securing this treasure in my fragile earthen vessel. I hand them over to the Blessed Virgin Mary to keep  safely for me.  Nothing in her safekeeping can be touched by the enemy of mankind.
