Yet, O Lord, you are our Father; we are the clay, and you are our potter; we are all the work of your hand.
For we do not proclaim ourselves; we proclaim Jesus Christ as Lord and ourselves as your slaves for Jesus' sake. For it is the God who said, 'Let light shine out of darkness', who has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ. But we have this treasure in clay jars, so that it may be made clear that this extraordinary power belongs to God and does not come from us.
2 Corinthians 4.5-7
