Ants have nests, but the ants will leave if the nest is toppled. These two sisters—Ruth Lee and Peace Wang—were skillful in overturning the "nests." No matter which household had problems, as long as these two sisters handled them, everything was solved. Hence, the work is difficult if no one leads the sisters. The experienced sisters need to be able to lead the sisters and teach them at the same time. Ruth Lee was truly apt to teach. She wrote hymn #127 in our Chinese hymnal. This hymn was written in a skillful and precise manner. From it we can tell that she was a teacher, one who was apt to teach.
