I think that if someone were really interested in trying to run magic as this amazingly powerful force, you would have to limit it in some way.
Make magic extremely rare: if it is this powerful, and it were common, then everybody would be using it, or everybody would find a way to counter it (or almost everybody woudl be dead or slaves).
Make it extremely difficult to learn or practice: to learn the magical arts, you must spend years in servitude to a master who will always be sure that you cannot surpass his ability and challenge him, or: you must make a sacrifice of your own lifeforce to power the spells.
Make it difficult to deal with: magic is so powerful that the common man fears it like he fears the devil. Practicioners of magic find themselves shunned, or mobs of torch and farm-implement bearing commoners arrive to burn the mage's home to the ground.
