While bombmaniac is correct that one should view the ability to keep the Torah as a privilege, one mustn’t lose sight of the fact that it is a mandatory privlege, not an option.
The Balei Musar talk about the fact that while it may be that “ahavas Hashem” is a greater darga then yira, still one must have a combination of both. When one has a relationship based exclusivley on ahava he may come to think that there is room to be a little less careful in his obligations due to the great love Hashem has for him, which will cause Hashem to be forgiving, which is not the case as explained by Nesilas Yeshorim.
