They spoke of the temporarily quiet Atlantic, and He [‘Abdu’l-Baha] said: "One must ride in the Ship of God; for this life is a stormy sea, and all the people on earth - that is, over two billion souls - will drown in it before a hundred years have passed. All, except those who ride in the Ship of God. Those will be saved."
