Sung was sometimes so excited that he often jumped onto the pulpit to preach; in the middle of the sermon he would always sing a hymn for up to twenty or thirty minutes. John Sung also made use of props during sermons. On one occasion during a sermon, he brought a coffin, placed it under the pulpit, and shouted, "Get rich, get rich, get the coffin!". (This was a play on words in the original Chinese, used to convey the idea that pursuing money will not bring you eternal life.) After exclaiming this statement, he then went and lay down in the coffin himself.
