But truly I am full of power by the spirit of the LORD, and of judgment, and of might, to declare to Jacob his transgression…
The three gifts, power, judgment, might, are the fruits of the one Spirit of God, through whom the prophet was filled with them. Of these, power is always strength residing in the person, whether it be the "power, or might of wisdom" of Almighty God Himself, or power which He imparts or implants. But it is always power lodged in the person, to be put forth on him. Here it is Divine power, given through God the Holy Ghost, to accomplish that for which He was sent. "Judgment" is, from its form, not so much discernment in the human being as "the thing judged," pronounced by God, the righteous judgment of God, and righteous judgment in man conformably therewith. "Might" is courage or boldness to deliver the message of God; not awed or hindered by any adversaries. "Whoso is so strengthened and arrayed uttereth fiery words, whereby hearers' hearts are moved and changed. But whoso speaketh of his own mind doth good neither to himself nor others." So then, of these three gifts, power expresses the Divine might lodged in him; judgment, the substance of what he had to deliver; might or courage, the strength to deliver it in face of human power, persecution, ridicule, death. These gifts the prophets know are not their own, but are from the Spirit of God, and are by Him inspired into them. Such was the spirit of Elijah, of John Baptist, of Paul, of the apostles.
