His Subjects 

His subjects are every divine being, every human being and all creation itself.

(See also His Kingdom)

1 Corinthians 15:27-28

[27] For he hath put all things under his feet. But when he saith, all things are put under him, it is manifest that he is excepted, which did put all things under him.
[28] And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.

Colossians 2:15

And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
