What's this line mean? Are they dead?
Native speaker’s answer
This line means they're comparing life on earth to "heaven," saying that it's as good as "heaven" is! So they're not dead, life is just as good as it would be in heaven, metaphorically, since heaven is often related to "good" things or feeling good. Ex: This massage is heavenly. Ex: The kid walked into the giant candy store and thought he was in heaven. Ex: I felt like heaven when I was with her.
