Charles Ellicott Commentary Isaiah 64:8

"But now, O Jehovah, thou art our Father; we are the clay, and thou our potter; and we all are the work of thy hand." — Isaiah 64:8 (ASV)

We are the clay, and you our potter ... —Commonly, partly, perhaps, from St. Paul’s application of the image in Romans 9:20-21, and Isaiah’s own use of it in Isaiah 29:16, we associate the idea of the potter with that of simple arbitrary sovereignty.

Here, however , another aspect is presented to us, and the power of the Great Potter is made the ground of prayer. The “clay” entreats Him to fashion it according to His will, and has faith in His readiness, as well as His power, to comply with that prayer. The thought of the “potter” becomes, in this aspect of it, one with that of the Fatherhood of God.
