Dear Truthsearcher,
Welcome to the board, and please be assured that, over time, your questions will receive satisfactory answers. The notion that God recognizes the prayers of JW's only in the circumstance you have described prevails. God's spirit, direction and blessing must be invoked by the Witness presiding over the study. Any allowance of the dread other option would smack of interfaith and Jehovah's displeasure. Well, once I got past all that, I began to feel right at home with, let's say, having dinner at a client's home, joining hands and bowing my head while the young son or father offered the blessing. And sometimes I would be asked to pray. No longer do I fear the strike of lightning during such blessed occasions. With the help of JWD, allow yourself time to figure all these things out.
Yours truly,
CoCo
