Joel 2:13 And rend your heart, and not your garments, And turn unto the LORD your God: For he is gracious and merciful, Slow to anger, and of great kindness, And repenteth him of the evil.God wanted them to have a broken heart, a heart that was changed. God wanted a heart that desired Him. They didn’t need external symbols but internal reality. They needed to turn from themselves, their sin, etc to God. They needed to know who God is and how He is. He is full of grace. He is full of mercy. He is slow to get angry. He is of great kindness. He doesn’t like to see people hurt. What a God He is. How wonderful and kind. How can you not turn to a God like Him.
