O house of Israel, cannot I do with you as this potter?
says the LORD.
Behold, as the clay is in the potter's hand, so are you in my hand, O house of Israel.
All Commentaries on Jeremiah 18:6 Go To Jeremiah 18
John Chrysostom
AD 407
When, therefore, God speaks of an irremediable calamity, he does not say vessels of the potter, but an earthen vessel. When, for instance, he wished to teach the prophet and the Jews that he delivered up the city to an irremediable calamity, he bade him take an earthen wine vessel, and crush it before all the people and say, “Thus shall this city be destroyed, be broken in pieces.” But when he wishes to hold out good hopes to them, he brings the prophet to a pottery and does not show him an earthen vessel but shows him a vessel of clay, which was in the hands of the potter, falling to the ground. He brings him to saying, “If this potter has taken up and remodeled his vessel that has fallen, shall I not much rather be able to restore you when you have fallen?” It is possible therefore for God not only to restore those who are made of clay, through the washing of regeneration, but also to bring back again to their original state, on their careful repentance, those who have received the power of the Spirit and have fallen from grace into ruin.
