When Merlin arrived to Camelot he was naive about his purpose and he didn't know that he was Emyrs the great sorcerer. All that he knew was that he has magic. With that being said, he did not know enough to embrace all his power. It's all about confidence and the wisdom to know who you really are. Being young and not having someone like his father to tell him from the very beginning kept him from knowing his true power. Until now Merlin has been in the dark and now that he is in the light he can wield his full power. He is the magic -- if he is magic itself no one or anything can take it away.

If you recall when Alator and Finna where bowing to him. Merlin was like don't do that, because he did not understand -- he did not think of himself to be all that powerful. He knew he had power, but not like the power he's going to have after he busts out of that cave.

Hopefully, the writers will how Merlin in his full form. Morgana will not be able to match his powers, because he's the magic.
