CandA,
Sorry to hear that you are going through this. It sounds way too familiar. If I were in your shoes, I would decline providing the help and let my JW family do what needs to be done. For your brother to state that you are being used by Jehovah to help them out and then expect that after you help them out you will be cast aside is ludicrous.
A quick story to help solidfy my position. A couple months ago, a brother was talking about how he had started to slow down in his service, you know, missing meetings and service, signs of complacency. He said that one night, to show how far he had gotten away from Jehovah, he was being bothered by only what he could refer to as "the demons." Because of this event, he started back to the meetings and service and now...he is fine.
I asked him, "So, the demons helped you get back to Jehovah? "
His reply, "Well, no. The "experience" of what happens when you draw away from Jehovah. That's what helped me."
"But, the experience was caused by the demons because you had drawn away right? They knew you were weak so they attacked you and now you're back. So, they really helped you get back to Jehovah. That's all I'm saying."
He was a bit perplexed, but conceded.
Point is. If the scripture is right, namely James 1:13, "For God cannot be tempted by evil, nor does he tempt anyone." Then what "union is there between good and evil" and "you cannot eat from the table of God and of the demons." I mean, if all those scriptures are true, then why in the world would they want anything at all to do with you if you are SOOOOOO evil! It is psychological abuse and manipulation.
It's like the guy that wins the lottery, gets called into a judicial committee for gambling and then gets public reproof only because he gives half of his money to the congregation. (Not that this has happened to my knowledge. It is simply a farsical way of describing the double standard.)
Just my thoughts,
SOP
