I suggest:
Modo te hominem esse oblitus recordaberis te deum [esse].
The key words are the participle oblitus ("one who has forgotten") and the verb recordaberis ("you will remember"). It says "only as someone who has forgotten you will remember".
Forgetting and remembering have objects expressed by an accusative with infinitive. I put the objects around the two key verbs to create a chiastic effect. You could translate te hominem esse as "that you are human" and the deum esse as "that you are god". The second esse is optional. So is the first one, really, but I would keep it for clarity. Choose what sounds best to you.
Google Translate is indeed horrible even with simple sentences. The only thing it seems to translate semi-reliably is individual words, and for that purpose online Latin dictionaries are far better.
