They that love beyond the world cannot be separated by it.
Death cannot kill what never dies.
Nor can spirits ever be divided, that love and live in the same divine principle, the root and record of their friendship.
If absence be not death, neither is theirs.
Death is but crossing the world, as friends do the seas; they live in one another still.
For they must needs be present, that love and live in that which is omnipresent.
In this divine glass they see face to face; and their converse is free, as well as pure.
This is the comfort of friends, that though they may be said to die, yet their friendship and society are, in the best sense, ever present, because immortal.

This poem was at the beginning of Deathly Hallows, and I think it fits with Snape just as well as the rest of the book.
Voldemort may have killed Lily, but that didn't sever what was left of their friendship, even if neither of them knew the other still cared, and it didn't stop Snape from loving her. It wasn't until Lily's life was threatened that Snape realized what a mistake he'd made, how stupid he'd been in his life... His love for her was immortal, and his love for her is what kept so many people safe, even after he was killed by Voldemort.
