Heaven, [comma] a place of joy and happiness,
Where anger and hate never is,
A place where we live in prosperity with our friends and posterity, >> these words sound too much alike. I would get rid of 'posterity'.
A place where no serpents lies,
And no love [could] ever die.
Hell, a place of hate and strife
[s]Here[/s][In hell] can exist no life
A place where we have neither family nor friends
A place where suffering never ends,
A place where the serpent with all his might [new line]
blocks out [all] the light.
