Irenaeus — Against Heresies 4.39.1-2
Offer him your heart soft and workable, and keep the form in which the Craftsman shaped you, keeping moisture in yourself so that you do not harden and lose the marks of his fingers.
Keeping the jointing, you will rise to the perfect. Soft clay is hidden in you by God’s craft. He will overlay you inside and out with pure gold and silver, and adorn you until the King himself desires your beauty.
But if you harden at once and spit out his art and prove thankless that you were made human, you lose both his art and life. To make belongs to God’s kindness; to be made belongs to human nature. Hand him what is yours — faith in him and subjection — and you will receive his art and be a perfect work of God.
