God’s purpose in using the frailty of flesh to contain the glory of the gospel is to testify to Himself, not to man. Jars of clay testify that salvation comes by the power of God, not the power of man, by the work of God, not the work of man, by the will of God, not the will of man, by the purpose of God not the purpose of man, for the glory of God not the glory of man, because of the truth of God not because of the intellect of man.

Salvation comes not through the work or might of men. Salvation comes through the power of God alone. I am just a jar of clay!
