104 And so He needed no helper. For He needed none when He made the world, so as to need none when He would redeem it. No legate, no messenger, but the Lord Himself made it whole. “He spoke and it was done.” The Lord Himself made it whole, Himself in every part, because all things were by Him. For who should help Him in Whom all things were created and by Whom all things consist? Who should help Him Who makes all things in a moment, and raises the dead at the last trump? The “last,” not as though He could not raise them at the first, or the second, or the third, but an order is observed, not that a difficulty may be at last overcome, but that the prescribed number be accomplished.
