They have the 'Truth' because they live by their interpretation of the bible?
Well, the bible is a Catholic book that they put together for their liturgical services. It is not a guide to Christianity, it only provides examples and some rules of Christianity.
Out of 30k-40k different sects of Christianity, only one was started by Jesus and can be traced back to the apostles. His church gave the world hospitals, universities, homeless shelters, foodbanks, and invented human rights for all based solely on all people being in the image and likeness of God.
JWs? They go door to door restoring God's name is the best fruits that they have?
Historical reality proves that the WTS does not have the 'Truth'
