The dramatic conclusion of Moon Knight episode 6 revealed Khonshu and his avatar are much weaker than Ammit and Arthur Harrow.  

Back in 2011, Marvel Studios trod softly when introducing their first MCU pantheon, the Asgardians; they hinted these cosmic beings were actually ancient aliens rather than true gods 

Thor tossing out a line about coming from a place where science and magic were one and the same thing. Moon Knight, however, took a very different approach with the Egyptian gods.

Moon Knight built up to a war in heaven between the gods Khonshu and Ammit, as their avatars fought it out on Earth as well.  

Curiously, though, it's notable that Ammit and her avatar Arthur Harrow seemed much more powerful than any of the other gods 

Ammit would have destroyed Khonshu had Moon Knight not teamed up with the new avatar of Tarewet, Scarlet Scarab, to perform a ritual that trapped her inside her host and left her vulnerable. 

The power difference between these two divine beings was quite remarkable - but, fortunately, it's easy to explain.

Fortunately, that particular god seems not to be malevolent, meaning she won't become a threat as the story of Moon Knight continues.
