2 Corinthians 4:7

But we have this treasure in earthen vessels, that the exceeding greatness of the power may be of God, and not from ourselves [We, in our mortal bodies, hold the divine and heavenly truth. God has thus committed his gospel to men that it may be evident to all that it is from him. The power of the gospel so transcends that of the human agent who preaches it as to make it apparent to all that the preacher is but an agent performing duties which are beyond the compass of his own unaided faculties. Farrar sees in this a reference to the torches of Gideon's pitchers, but the word "treasure" evidently changes the figure, so that Paul no longer speaks of the gospel as a light. Besides, the Gideon incident conveys the idea of concealment, which is not in Paul's thoughts. The apostle is here supposing that some one will object to his high claims for the Christian ministry, asserting that the humiliations and sufferings endured by the apostle refute the idea that he can be an ambassador of God. His answer is that God put the treasure in an earthen vessel in order that the survival of the perishing vessel when subjected to all manner of vicissitudes might prove the value, in the sight of God, of the treasure within it];
