'They will eat but not have enough; they will engage in prostitution but not increase, because they have deserted the Lord to give themselves to prostitution, to old wine and new, which take away the understanding of my people. They consult a wooden idol and are answered by a stick of wood. A spirit of prostitution leads them astray, they are unfaithful to their God.'
In this passage, God tells of how He will remove His hand of provision from the people that have abandoned Him. Because they forgot that God is the source of all good things, He will stop providing the food they need and will even stop giving them children. They have abandoned the pursuit of righteousness and turned to satisfying the flesh with sex and alcohol. They even turned to idols for answers instead of the Creator of the universe. The same "spirit of prostitution" described in this passage is at work today and even more so as we have so many more things such as cars, homes, and other possessions that can become idols if we do not guard our hearts. God removed His blessing from the people of Israel at this time and we can be sure that He will do the same thing today. God loves us enough to take away some of our possessions if they start to become more important to us than He is.
