I (voluntarily) learned this prayer in German when I (voluntarily) created an Indepedent Study in Theological German many years ago. I still pray it in German. The version I learned was:

Komm, Herr Jesu
Sei user Gast
Und segne was Du uns
Aus gnaden bescheret hast. Amen

That last part is, somewhat literally:

"Bless what you have out of grace bestowed unto us. Amen."

Fitting rhyme and meter into another language means you usually have to let something go, as far as exactness. So, "gifts" aren't mentioned in German, "grace" and "bestowing" aren''t mentioned in English. (Though I guess you could say that "bestowing" is like "giving", which is related to "gift.")
