"'How can you say, "I am not defiled; I have not run after the Baals"? See how you behaved in the valley; consider what you have done. You are a swift she-camel running here and there, a wild donkey accustomed to the desert, sniffing the wind in her craving - in her heat who can restrain her? Any males that pursue her need not tire themselves; at mating time they will find her.'" NIV translation
When the biological clock is ticking in a female animal, they will chase after males to mate. The males do not have to work too hard. That is what God compares their idolatry to. It is the same for us and what Paul described as the battle inside us between the flesh and the spirit. (see Romans 7)
"'Do not run until your feet are bare and your throat is dry. But you said, "It's no use! I love foreign gods, and I must go after them." As a thief is disgraced when he is caught, so the house of Israel is disgraced - they, their kings and their officials, their priests and their prophets.'" NIV translation
God urges His people to resist the flesh but their reaction is to give in. We see that this leads to disgrace when the deeds are exposed. We, too, face this battle on a daily basis but we have the victory through Jesus Christ. If we grab hold of that victory, we have the power to resist through the Holy Spirit.
"'They say to wood, "you are my father," and to stone, "You gave me birth." They have turned their backs to me and not their faces; yet when they are in trouble, they say, "Come and save us!"'" NIV translation
The people had forgotten that it was God who created them but, when trouble came, they asked God for help. The same is true today as many will try to put God in the closet and only bring Him out to pray when there is an illness or a physical need. The Lord wants a relationship of constantly walking and talking with Him and anything less is idolatry as described in this passage.
"Where then are the gods you made for yourselves? Let them come if they can save you when you are in trouble! For you have as many gods as you have towns, O Judah. 'Why do you bring charges against me? You have all rebelled against me,' declares the Lord." NIV translation
Their sin (idolatry) separated them from God and yet they blamed God for abandoning them. In fact, God never left them; they had turned away and left God. Many of us do the same type of thing today as we trust in our own efforts until we get into a mess and then we blame God for our being in a mess. God allows our rebellion to lead to bad things on hope that we will repent and come back to Him.
