Woe unto him that striveth with his Maker! Let the potsherd strive with the potsherds of the earth. Shall the clay say to him that fashioneth it, What makest thou? or thy work, He hath no hands? (Isaiah 45:9)
This verse specifically speaks against people who are aware of God yet question God's involvement in His work. Free Willers do this. Free Will is the notion that God has no hands working the man's will.
Try reading Jeremiah 18, the potter and clay chapter.
There’s no individual persons on the potters wheel - it’s the nation of Israel - God remolded them because of their continued sin and disobedience.
The Potter and the Clay.
Jer 18:1 The word which came to Jeremiah from the LORD, saying,
Jer 18:2 Arise, and go down to the potter's house, and there I will cause thee to hear my words.
Jer 18:3 Then I went down to the potter's house, and, behold, he wrought a work on the wheels.
Jer 18:4 And the vessel that he made of clay was marred in the hand of the potter: so he made it again another vessel, as seemed good to the potter to make it.
Jer 18:5 Then the word of the LORD came to me, saying,
Jer 18:6 O house of ISRAEL , cannot I do with you as this potter? saith the LORD. Behold, as the clay is in the potter's hand, so are ye in mine hand, O house of Israel.
Israel’s continual sins caused God to reshape Israel into another vessel, as the next verse is an example of that:
Israel is on the potters wheel, being reformed into a different vessel, due to their sin and rebellion.
2Ti 2:20 Now in a great house there are not only vessels of gold and silver but also of wood and clay, some for honorable use, some for dishonorable.
2Ti 2:21 Therefore, if anyone cleanses himself from what is dishonorable, he will be a vessel for honorable use, set apart as holy, useful to the master of the house, ready for every good work.
It’s what we do that determines if we become vessels of honor or dishonor.
I know the fact that it is our will that’s involved there, is very inconvenient to Calvinism and to the philosophy of fatalistic determinism known as reformed doctrine.
