THINKING OUT LOUD SENTENCES
1. Sweep you off (of) your feet
This sentence (in this song) means "to carry someone", that's why the autor it's using it to say: "even when we were older, and I couldn't raise you up or hold you in my arms (carry you) i'll be loving you the same way i do now, will you?" but also It's an english expression reffering to the feeling that one gets when completely taken by someone, carried away, swept away (all emotionally), like making someone fall in love with you in a short amount of time, and, sometimes it's applied in a more broad context like: to be surprised, enthralled, exhilarated.
Example: Musicians can be swept off their feet by a new musical composition.
