Even though I was not a Christian, I was allowed to join their travel after serious consideration (I was rejected twice; when I had given up, they contacted me the night before their travel started).
Aunque yo no era cristiana, se me permitió unirme a su viaje después de considerarlo muy seriamente (Fuí rechazada dos veces, cuando me había dado por vencida, contactaron conmigo la noche antes que su viaje iniciara).
