John Chrysostom
He descended, he says, into the very lowest divisions of the earth, beyond which there are no others. And He ascended above all, beyond which there is nothing else. This signifies His power and authority, because even before this all things were filled by Him. What he says elsewhere, "Therefore God also highly exalted Him" (Phil 2:9), he expresses here by the words, "He who descended is the same who also ascended." The descent into the lower parts of the earth did Him no harm at all, and in no way prevented Him from being above the heavens. Thus the more one humbles himself, the more he is exalted. So it is with water: the deeper one plunges into it, the more strongly it raises him upward. And the nearer the distance from which an arrow is shot, the more surely it hits the target. So also it is with humility. Yet when we speak of God's ascent, we must first conceive His descent. With regard to man, this is not necessary.
