Yesu ananena kuti uthenga wabwino wa Ufumu udzalalikidwa kwa anthu padziko lonse lapansi. (Mateyu 24:14) Kuyambira mu 1909, mabuku othandiza anthu kumvetsa Baibulo ofalitsidwa ndi a Mboni za Yehova anayamba kumasuliridwa m’Chisipanishi. Mabukuwa akhala akuthandiza anthu padziko lonse lapansi kumvetsa uthenga wa Ufumu m’chinenero chawo. Panopa Chisipanishi ndi chinenero chachiwiri chomwe anthu ambiri amalankhula monga chinenero chawo choyambirira, poyerekezera ndi Chitchainizi chomwe chimalankhulidwa ndi anthu ambiri zedi monga chinenero chawo choyambirira. Masiku ano, anthu pafupifupi hafu biliyoni amalankhula Chisipanishi.

Cholinga chathu n’chakuti tizimasulira m’njira yoti munthu wina aliyense, kaya maphunziro ake ndi otani, kaya ndi wolemera kapena wosauka, azimva mosavuta mabuku athu.” Pofuna kuti zimenezi zitheke, anthu a m’gulu logwira ntchito yomasulira mabukuwa ndi ochokera m’mayiko osiyanasiyana monga Argentina, Colombia, El Salvador, Guatemala, Mexico, Puerto Rico, United States, Uruguay, Venezuela ndi Spain.
