This will probably sound controversial to anyone who is still religiously inclined so I apologies upfront and do not mean any offence by it. It's just my 'pondering'.
I was thinking about all the times that I heard form the platform and read in the WatchTower that Jesus made the greatest sacrifice ever in history by giving his life in exchange for all minkind, to die for our sins etc.
But even if this were true, would it be such a great sacrifice?
Giving one life in exchange for thousands ... millions ... billions seems to be not too big a sacrifice for the return and one that many people would make today. In fact, people give their lives for much less ...
How about, instead, the unknown soldier who stays behind knowing he will die but trying to save his comrades.
... the fireman who dies saving the life of another
... or the passerby who rescues a child but dies in the process.
None of these 'know' like Jesus did that they will be straight back up to heaven and receiving the 'keys to the kingdom' or that they will be saving billions of souls but they make the sacrifice still and to me, this is a much greater sacrifice.
