Theos and Theon are the same word in different cases. Theos is nominative, Theon is accusative. It means the same exact thing in either case. The only difference is the role it plays in the sentence. Nominative case is generally the subject, while the accusative case is the direct object.
And by the way,1) Satan is called “ho theos” -the god of this world. 2) Jesus didn’t and wouldn’t disobey his Father’s commands, and 3) theoretically speaking, if Jesus disobeyed, it doesn’t mean that God would not love him. After all, we disobey and God still loves us; are we greater than Jesus in God’s eyes?
