Jeremiah 9:12-14

Who is wise enough to understand all this?
Who has been instructed by the Lord and can explain it to others?
Why has the land been ruined so completely that no one even dares to travel through it?
The Lord replies, "This has happened because my people have abandoned the instructions I gave them; they have refused to obey my law.
Instead, they have stubbornly followed their own desires and worshiped the images of Baal, as their ancestors taught them.   

  Now there is an opportunity for apostate Ahab and pagan Jezebel to test the power of their gods and to prove the word of Elijah false. Jezebel's prophets are numbered by hundreds. Against them all stands Elijah, alone. His word has locked heaven. If Baal can give dew and rain, and cause vegetation to flourish; if he can cause the brooks and streams to flow on as usual, independent of the treasures of heaven in the showers of rain, then let the king of Israel worship him and the people say that he is God.

Jeremiah 7:23-24
    This is what I told them: 'Obey me, and I will be your God, and you will be my people. Only do as I say, and all will be well!'
"But my people would not listen to me. They kept on doing whatever they wanted, following the stubborn desires of their evil hearts. They went backward instead of forward.
