I can of myself do nothing. As I hear, I judge, and my judgment is righteous; because I don't seek my own will, but the will of my Father who sent me.
I judge - I determine or decide. This was true respecting the institutions and doctrines of religion, and it will be true respecting the sentence which he will pass on mankind at the day of judgment. He will decide their destiny according to what the Father wills and wishes - that is, according to justice.
