There are sects that hold that position, mostly associated with Calvinism. In those sects, if you're not showing gratitude by good works, then you're probably not one of the elect.

If you're convinced that you're not one of the elect, and you've given up, then you've failed to have faith, so it becomes a self-fulfilling prophecy. Getting faith doesn't guarantee you're one of the elect, but not having it guarantees that you're not.

So an attitude like yours might work anyway, if you happen to be one of the elect, but the odds aren't in your favor.
