Roberta, please have a look at the examples below:
(1) God gives you your life. (Remark: it is with normal grammar)
(2) God bless! (Remark: we don't want to say "God blesses!", do we? It is different to normal grammar.)
So expressing "God award hard-working people" is the same of expressing "God awards hard-working people".
Because God is supernatural and above anything .
