What Injustice? Jeremiah 2:5

Thus says the Lord. "What injustice did your fathers find in Me that they went far from Me and walked after emptiness and became empty?" Jeremiah 2:5

God set Israel apart for holy purposes. His people became faithless. They were once loyal and faithful. They once listened and obeyed the covenant. Now, they are empty and worthless, putting their trust in worthless idols. What happened? God asks if it was His doing. 

Jeremiah's confrontation is God building a case against the people. Who is responsible? Did God let the ball drop or was Israel at fault? 

How do empty pursuits affect the person who has made a commitment to follow God?
