the hour of his judgment has come

Here "the hour" represents the time that has been chosen for something, and the hour having "come" is a metaphor for now being the chosen time. The idea of "judgment" can be expressed with a verb. Alternate translation: "now is the time that God has chosen for judgment" or "it is now the time for God to judge people" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-abstractnouns)
