I am.That our Lord by this expression asserted his divinity and eternal existence, as the great I AM, appears evident from the use of the present tense, instead of the past tense, from its being in answer to the Jews, who enquired whether he had seen Abraham, and from its being thus understood by the multitude, who were exasperated at it to such a degree that they took up stones to stone him. The ancient Jews not only believed that the Messiah was superior to and Lord of all the patriarchs, and even of angels, but that his celestial nature existed with God from whom it emanated, before the creation, and that the creation was effected by his ministry.
