Even those who had preached incorrectly, “soon became converted, and were convinced of the error they were in.” That leads to peace. Sadly, as with most Nephite times of peace, it doesn’t last for long. The sign had been given in the ninety-second year. By the end of the next year, the Gadiantons were reasserting themselves. By mentioning the Gadiantons, Mormon signals that worse times are coming.
Less than two years passed, and Nephite apostasy was beginning again.
