[[I have always wondered how happy one can be in Heaven, when able to see loved ones suffering downstairs.]]
See my post above- many feel that there is no remembrance because there is no sorrow in heaven- to remember loved ones back on earth would bring sorrow it is argued- I personally think they might have a point- (it’s not that they won’t recognize their saved loved ones when they pass on and enter heaven too though- they should and rejoice with them, but until that time? I just don’t know, but think the memory is not present while their loved ones are back on earth- either that or they just look forward to meeting them again)
Perhaps there is a 'great cloud of witnesses', cheering on the faithful in their race. Regardless, we shouldn't get too hung up on whether departed loved ones can see us, but rather that if the departed family or friend, fought the good fight, was faithful to Christ and now rests in him, we can do so as well through Christ as they did! Take heart and run the race with renewed spirit.
