You are correct the wbts is false in it's reasoning.In the June 1/08 wt they ask "Does it matter how we worship God? We may ask ourselves:What kind of worship does God approve?How can I draw close to God?And what should I personally do to worship God in an acceptable way?"Jw are happy to deceive you.
You see there is nothing in those questions about Jesus,why he came, why he died for us sinners.
