This is the word that came to Jeremiah from the Lord: "Go down to the potter's house, and there I will give you my message." So I went down to the potter's house, and I saw him working at the wheel. But the pot he was shaping from the clay was marred in his hands; so the potter formed it into another pot, shaping it as seemed best to him. Then the word of the Lord came to me: "O house of Israel, can I not do with you as this potter does?" declares the Lord. "Like clay in the hand of the potter, so are you in my hand, O house of Israel. If at any time I announce that a nation or kingdom is to be uprooted, torn down and destroyed, and if that nation I warned repents of its evil, then I will relent and not inflict on it the disaster I had planned. And if at another time I announce that a nation or kingdom is to be built up and planted, and if it does evil in my sight and does not obey me, then I will reconsider the good I had intended to do for it. (Jeremiah 18:1-10)
There are some false ideas of God out there that make Him into a tyrannical dictator that controls the universe on puppet strings. Everything is pre-determined and pre-destined. God has created a race of the "chosen" whom He loves and who He will save, as well as a race of the "damned" who cannot get on God's good side no matter what. Generally, you can identify the chosen by their sparkling smiles, good grammar, and clean cut appearance. The damned have tattoos, vulgar language, and they like to smoke and drink. God, it turns out, is the producer of "Leave it to Beaver" and other wholesome 50's sitcoms, and if we do not act like that, then we are going straight to hell.
