We treat God in ways we would never condone in human relationships. God asked a question: Would society accept marriages where couples divorced and remarried, only to repeat the process again and again? A land that practiced such abominable behavior would be morally and spiritually polluted into ruin. No marriage could survive such disloyalty and disregard to commitment. Yet this is how people assumed they could relate to God.
The people were regularly forsaking their commitment to God and giving their hearts to idols. They might eventually return for a time, but would inevitably forsake their Lord once more. The land had become polluted with broken promises and fickle commitment.
Nevertheless, God’s invitation was tor His people to return to Him. Not in a casual, insincere manner, but with all of their hearts.
Our land has become polluted with spiritual betrayal and insincere confession. People occasionally return, but not with all of their heart. Even as they are returning to God they are already sowing the seeds of their next apostasy. For our land to be purified, God’s people must return to God with all of their heart.
