They offer sacrifices, even more than before, but their hearts are not repentant
When your heart is far from God, then your sacrifices:
What God is looking for is humble, true, heartfelt, and honest repentance. He doesn't want sacrifices. He doesn't want you to buy your way out of the mess you've made. He wants you to turn your heart to Him and repent: Change your ways . . . and really mean it.
