(1st.) His fitness to save, — his being ἱκανὸς, a fit Saviour, suited to the work; and this, I say, is from his grace of union. The uniting of the natures of God and man in one person made him fit to be a Saviour to the uttermost. He lays his hand upon God, by partaking of his nature, Zech. xiii. 7; and he lays his hand upon us, by being partaker of our nature, Heb. ii. 14, 16: and so becomes a days-man, or umpire between both. By this means he fills up all the distance that was made by sin between God and us; and we who were far off are made nigh in him. Upon this account it was that he had room enough in his breast to receive, and power enough in his spirit to bear, all the wrath that was prepared for us. Sin was infinite only in respect of the object; and punishment was infinite in respect of the subject. This ariseth from his union.
