This chapter reminds me of a story in the Book of Joshua. Joshua goes to complain to God about things not going so well, even though he is doing as God instructed. (Paraphrasing) Wait a minute, God says. Joshua, there is sin in the camp. In Jeremiah 12, Jeremiah is questioning God about a lack of justice. God’s reply is about Israel’s faithlessness, her idolatry and the abandonment of God. Because of her infidelity, God will have justice – justice against His beloved Israel.
Application for us? Are you planning something and coming up against multiple obstacles? Poor health? Lack of money? Lack of interest? Outright antagonism? Check for sin in your heart. If it is there, repent and find forgiveness. Ask God to reveal sin wherever it is, and pray for repentance
