Buddhism is not a practice of isolating ourselves in our homes and doing our daily service, and having it stop there. How can we expect our efforts of sharing Buddhism with others to be effective if we ourselves have no connection to all of the Three Jewels?
No matter how hard one tries, if a person is not himself fully embracing the entire Lotus Sutra of Buddha, Dharma, and Sangha then it is impossible to teach others and to fully share with others the truth, the entire truth of the Lotus Sutra. The Lotus Sutra does not stop at one’s own life. The Buddha demonstrates this when he asks who will teach this on into the future.
