As for the message that you have spoken to us in the name of the LORD, we are not going to listen to you! But rather we will certainly carry out every word that has proceeded from our mouths, by burning sacrifices to the queen of heaven and pouring out drink offerings to her, just as we ourselves, our forefathers, our kings and our princes did in the cities of Judah and in the streets of Jerusalem; for then we had plenty of food and were well off and saw no misfortune. But since we stopped burning sacrifices to the queen of heaven and pouring out drink offerings to her, we have lacked everything and have met our end by the sword and by famine.
The Israelites had just experienced a horrible time of famine, war, and persecution. God had already spoken through the prophet Jeremiah that it would come because of their turning from Him and committing spiritual adultery with the "queen of heaven." No one believed him though, and continued in their ways, trusting God would still protect them despite their false idol worship. When the testing did come, they turned from their idols and sought God, but now it was too late. God's judgment had come and they were not repentant, only remorseful for their mistakes. This is shown in the verse above in that when God tells them to stay in the land and not go down to Egypt. They did not associate their suffering with their spiritual adultery but rather their abandonment of it! Their past had caused their current pain but they sought to return to their past sins, glorifying it's joy and fulfillment of their desires. Don't allow yourself to believe this lie either. We can sometimes be tempted to look back fondly on our sinful life and remember the good things, forgetting the bad things like pain, suffering, and lack of real fulfillment. Remember the good things you have when you follow God, even if it is hard for a season; eternal life, forgiveness, and the love of the Creator of the Universe! That far outweighs even the greatest pleasure of your past sin life. Don't forget this!
