Fisherman 'Give examples where the wts uses the term spiritual to apply it to something material?'
The Watchtower Society confuses material things, such as congregation meetings and Bible knowledge, with spirituality.
Contributing to the Spiritual Paradise
Most people enjoy visiting a park or garden. They like to walk through it or perhaps sit on a bench and enjoy the surroundings. In a similar way, many enjoy associating with Jehovah’s Witnesses. They find the fellowship refreshing, peaceful, and restorative. However, a beautiful garden needs to be tended if it is to continue to be paradisaic. Similarly, the spiritual paradise exists in this very nonparadisaic world only because Jehovah’s Witnesses cultivate it, and God blesses their efforts. How, then, can one make a meaningful contribution to that paradise?
First, you need to associate with a congregation of Jehovah’s Witnesses, study the Bible with them, and acquire the Bible knowledge that is the basis of the spiritual paradise. Carla noted: “There is no spiritual paradise without spiritual food.” This includes reading God’s Word regularly and thinking about what you read. The knowledge acquired will draw you closer to Jehovah God, and you will come to love him.
