Matthew Poole and continuators on John 5:30

30 I can of my own self do nothing : as I hear, I judge; and my judgment is just , because I seek not my own will, but the will of the Father which hath sent me .

Neither considered as God, or as Mediator. As God the Father and Christ were one, and what one Person in the Holy Trinity doth, all do: so that he did nothing in that capacity separately from his Father. As Mediator, he did nothing of his self; he finished the work which his Father gave him to do.

As the Father revealed his Will to him for the administration of his Mediatory Kingdom in the World, so he Judged: And therefore his Judgment must necessarily be just and true

for his Will was not a Will proper to himself, so as it was not also common to his Father, but divers from the Will of his Father; but as his Essence, so his Will was the same with his Father; and he being by the Father sent into the World to do his Will, accordingly did nothing as Mediator but what was his Fathers Will as well as his own; in nothing divers from his Fathers.
