Now, I'll explain what it means
It's basically about how bad things will happen in your life sometime, and you gotta accept that, and realize that you become who you are through the bad times. This isn't meant to be a christian song, although I do mention God a few times. What I am saying when I say "what kind of a God would do this to me" is "Why is this happening to me? If God loves me, why would he do this?" Then the chorus is the kind of resolve part .
