It is all parables, that is, what is unseen revealed.
Thus, in the case of marriage, after thousands of years what was unseen being seen, in the fulness of time Paul came to say regarding marriage, "This is a great mystery, but I speak concerning Christ and the church."
As for Jesus, the parable of the first Adam shows Jesus not only to be His own person as He is known to this world, but more importantly as being One with whom He is a part, just as Eve was in the world as her own person, but according to God was only a part of Adam. Therefore, no longer being of the world, I speak of what is according to God rather than according to this world.
