I just had another thought, maybe you could think on this. There is a big difference between a religious person & a spiritual person. The Pharisees were R & that's why they were so unforgiving & ridged, made serving God a heavy burden for the people. Jesus was S so flexible, kind, forgiving etc. WTBTS are most definitely R. As far as the 3 way cord goes didn't Jeff Jako say at the R.C that those acting in harmony with the bible could also be said to speak for God. So if your applying the principles of scripture in the way you deal with your wife then you are a spiritual man, even if you choose not to be a religious one. Therefore she does not need to worry. You explain that to her & back it up with actions her confidence in you will grow.
