And the vessel that he made was marred, as clay, in the hand of the potter; and he made it again another vessel, as seemed good to the potter to make.
Jeremiah 18:4 (DARBY)
The potter did not continue working on the defective vessel to finish or improve it. But, with the same clay, he saw fit to make another vase. What I like about starting from scratch is making another vase as he saw fit.
I don't know if you understand what's going on at this level. The potter undertakes the same process as God. As much as we fail in our walk with God, as much as we refuse to live according to His will, He will begin to shape us again according to His good will. God will never say: I will abandon this vase because it is difficult to remake. We must understand that God has all eternity to start again.
Know this well, your emotions, your complaints and your tears will not change God's intention. Under no circumstances will He change His mind, because He will start again as often as He deems necessary, until you have reached the spiritual maturity that He expects of you.
