Well, I guess it depends on what one believes about the body of Christ, and being a member.
In multiple places in scripture, we are told believers belong to 'one body'. We are all members of this 'one body'. (Romans 12, 1Corinthians 10, 1Corinthians 12, Ephesians 3-5, Colossians 3). In fact, a lot of Scripture is spent drilling into our heads this understanding.
We are also told in scripture that nothing, including death can separate us from the love of Christ (Romans 8:38-39).
So if one does not believe that the saints in heaven are concerned about our welfare and suffer and rejoice with us, what does one believe about the 'one body'?
Seems to me there are only two conclusions. First, there is not one body, but two -- one for those living on earth and one for those living in heaven. Two completely separate bodies, which is completely contradictory to scripture -- there is only one body.
The second conclusion would be that we are separated from this one body at death. Again, completely contradictory to scripture.
If one believes there is one body, and that we are not separated from this body at death (as Catholics do) then scripture is clear that members within the body care for each other and rejoice and suffer together. In fact, Paul says that "The eye cannot say to the hand, "I don't need you!" And the head cannot say to the feet, "I don't need you!"
However, this is exactly what people do when they tell those in heaven -- "we don't need you". We have Jesus, and that's all we need.
So the question is -- do you believe there is one body, and that death does not separate us from it? If so, then scripture says the saints in heaven indeed care for us. If not, please provide the scripture that supports your view that there are two bodies, or that we are no longer members of the one body at death.
