The creator of these comics is a Christian, with the message of them being a Christian message/allegory.
The message here is that if you disconnect yourself from God and try to live independent from God, you lose your purpose and/or are helpless to fulfill your "true purpose" (which, to a Christian, "true purpose" = serving/following God).
That said: I'd strongly suggest that people stop posting these comics and giving this guy attention. They're meant for Christians and are not really relevant to people outside of that.
EDIT: I made a (regrettable) visit to the website to satisfy my curiosity and found the title & description:
Absolute Freedom – God (in control of all things) gives us freedom to choose what to do, but we don't get to choose the outcome.
The puppeteer can make you cut your own ties at any time and leave you in a ditch 'cause you were kept a dependent weakling. The author is accidentally promoting self reliance, because that interpretation is not allowed to him or his public. Stupid comics.
Worse, it's an allegory for losing your faith in God. I visited the website and it's full of comics with similar messages. If you value your sanity, I suggest you stay away from the website.
If I recall correctly, Jonathan M Lam is a right wing very Christian cartoonist.
So in that context, God gave free will, the free will enables you to cut anything that ties you down, but, even the hand you use to cut yourself free, was controlled by God to begin with.
And once completely removed from God, you "insert some Christian bullshit".
Having free will doesn't mean you should use it bullshit.
given the 'atm robber comic' from the same cartoonist recently posted, i am guessing that it's somehow meant to represent becoming an atheist. you reject the strings of god and it makes you bad at dancing.
All the strings are loose and she's dancing perfectly fine and she's happy. But when she cuts those strings, which clearly weren't actually doing anything, she falls apart. So she needs that support even if it is mostly just for show.
