I think he was clearly being sarcastic. I think his point was that she was thrust into the situation against her will, and that moment (sarcastically) might as well have been the saber pushing her forward yet again.
Seriously, though, that’s supposed to be the moment she accepts her calling. Prior to that she refused the call by wanting to stay on Jakku and fleeing Maz’s castle.

JEDIT: Maybe, just maybe, someday my phone will let me post without horrible typos of spelling or grammar. I’d kill for Tapatalk integration.
