WRATH

HI
is 'wrath' a common word to use?
i have written a poem
i have used this word as

{ But the slightest thought of his going away
snatches all my happiness and makes me go astray

" it's the end of the magic if one day the wrath of god say
no longer on the earth my soul will then stay"}

the context is i am enjoying in present because someone has come into my life and i am afraid if he goes away what will happen
please give your valuable suggestions to make my poem impreessive
