How was Fingolfin able to wound Morgoth?

We all know the dude lost, but seriously. How was a regular elf able to harm the most powerful being in existence? When Sauron had his ring, he was unkillable, and I'm pretty sure Morgoth was more powerful than Sauron with the one ring. This shouldn't have even been a fight.

Two things factor into this. Firstly, Morgoth expended most of his power bringing evil and corruption into Middle Earth. Of all the Valar, he alone was bound to a physical form, and his power was but a shadow of what he was once capable of, though he was still mightier than any mortal creature.

On the other end, Fingolfin was considered one of the mightiest warriors of his kind. In the duel, while he managed to wound Morgoth several times, there was no possibility that Fingolfin could kill one of the Valar.
