During his twenties, Sundar Singh's Gospel work widened greatly, and long before he was thirty, his name and picture were familiar all over the Christian world. He described a struggle with Satan to retain his humility, but people described him as always human, approachable and humble, with a sense of fun and a love of nature. This character, with his illustrations from ordinary life, gave his addresses great impact. Many people said, "He not only looks like Jesus, he talks like Jesus must have talked." His talks and his personal speech were informed by his habitual early morning meditation, especially on the gospels. In 1918 he made a long tour of South India and Ceylon, and the following year he was invited to Burma, Malaya, China and Japan.
