For the truths are unique, and may have shadows and types, but no analogies.

At this moment I have no intuition, no intellectual diagram, of this article of the commission of all judgment to the Son, and therefore a multitude of plausible objections present themselves, which I cannot solve--nor do I expect to solve them till by faith I see the thing itself .-- Is not mercy an attribute of the Deity, as Deity, and not exclusively of the Person of the Son?

And therefore now it is given him to have life in himself, as the Father hath life in himself, as the original fountain of all life, by whom the Son himself lives: all life is derived from God, either by eternal generation, or procession, or creation; and thus Christ hath life in himself also; to the new creation he is the fountain of life: 'he quickeneth whom he will'.
The truths which hitherto had been metaphysical, then began to be historical.

The Eternal was to be manifested in time.
