On a few occasions I have heard people suggest that even if the saints in heaven do hear our prayers, they do not care about what goes on down here: in other words, the point is that even if they know we ask them to intercede for us, they won’t do it because earthly things do not matter to them anymore. While of course it is true that they are much more interested in enjoying God, it is just plain silly to say they do not care about us.
They cried out with a loud voice, “O Sovereign Lord, holy and true, how long before you will judge and avenge our blood on those who dwell upon the earth?” [Rev. 6:10]
If they care enough to ask for justice upon those who persecuted them, how much more likely is it that they care for those who (like them) love God enough that they also pray for them? We and they are the Body of Christ; will they not surely be all the more likely to honor our requests for their prayers on our behalf?
Of course they will.
