But after a while of begging, I conceded.
Why did you spend time begging? Remember, introductory clauses always modify the noun (or pronoun) directly after the comma, whether you intend them to or not.
hat energy, I believe, is the love felt by one who has been saved, the Holy Spirit entering the body.
I've mentioned this on other threads, but religious references in admissions essay carry a certain amount of risk with them. You can still keep them in, just be aware that, depending upon where you are applying, they may harm rather than help your admissions chances.
It was rather approaching someone and finding that person to be an exchange student or a FOB (pronounced "fahb," meaning "fresh off the boat") and didn't speak English.
I'd leave out the FOB reference, if I were you. The term seems more derogatory, as if it shouldn't really be thrown into an application essay.
