We learned that an angel appeared to Alma and his friends and told them to mend their ways. Alma was so astonished by his message that he fell to the ground and had to be carried back to his father's house by his friends. Alma the Younger could not move or speak for two days and two nights. When he finally regained his strength, he told his father that he had repented of his sins and that Heavenly Father had forgiven him. After that, he spent his time telling people to choose the right and teaching them true principles. We talked about the steps Alma the Younger had taken to repent.
We put together very tricky heart puzzles. Repentance is how we put the pieces back together when we have broken a commandment.
