I read your comments and it really touched me. I am one of Jehovah Witnesses and we follow strictly what the bible says. I would like to share a scripture with you. it is found at Ecclesiates chapter 9 verse 5.:
FOR THE LIVING ARE CONSCIENCE THAT THEY WILL DIE, BUT AS FOR THE DEAD, THEY ARE CONSCIENCE OF NOTHING AT ALL, NEITHER DO THEY ANYMORE HAVE WAGES, BECAUSE THE REMEBRANCE OF THEM HAS BEEN FORGOTTEN.
That scripture says that the dead are neither here or there but are unconscious. which means that they are sleeping. i also saw that you are having some problems with your sister in law. I too used to have problems with my husband then boyfriends family. I wondered why they constantly would always make comments and just be very negative.
I looked to the bible for comfort and found a very helpful scripture at Romans 12: 20-21
BUT IF YOUR ENEMY IS HUNGRY FEED HIM IF HE IS THIRSTY GIVE HIM SOMETHING TO DRINK, FOR BY DOING THIS YOU WILL HEAP FIERY COALS UPON HIS HEAD. DO NOT LET YOURSELF BE CONQUERED BY EVIL, BUT KEEP CONQUERING THE EVIL WITH GOOD.
So if your brothers family keeps acting nasty just apply those words and be kind to them no matter what. Maybe you can write a letter to her calling peace amongst yourselves. Well I hope I helped. Let me knw the result if you decide to take the advise.
