Revelations 21:4-5
(RSV)

...he will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning nor crying nor pain any more, for the former things have passed away.' And he who sat upon the throne said, 'Behold, I make all things new.' Also he said, 'Write this, for these words are trustworthy and true.

We should strive and actively participate in the reconciliation of God's Creation, until we reach a time where there will be no more suffering and pain. Choosing a plant-based diet is a testament of how much suffering we can alleviate, in humans and Godís animals.
