Like my signature says, our material short life is an (unique) opportunity to choose.
If you choose love, afther the death you'll have the perfect love in a different kind of existence. Obviously, God is love, so you'll live "into" God (but we're living in Him even now) in a perfect new different kind of reality (please don't tell me that's boring before we've tried it, ok?
)
If you choose egoism, well, you'll live in a hell of loneliness and selfishness...
