Tree should be healed by a Tree

There is a great hymn we sang for the Feast of the Elevation of the Cross. Here it is mentioned that Adam by means of a Tree was deceived, but that healing also came by means of a Tree. Quite profound:

Come, all you nations,
let us fall down in worship before the blessed Tree,
by which eternal justice has come to pass!
For he who deceived Adam by a Tree
is caught by the lure of the Cross;
and he who held under his tyranny the creature endowed by God with
royal dignity
is brought down in a headlong fall.
The serpent's venom is washed away by the blood of God,
and the curse of just condemnation is undone
when the Just One is condemned by an unjust judgment.
For it was fitting that the Tree should be healed by a Tree,
and that by the Passion of the passionless God
what was wrought on the Tree should destroy the passions of man,
who was condemned.
But glory to Your dread dispensation for our sakes, O Christ the King,
through which You have saved us all
since You are good and the Lover of mankind!

Fr. Stephen has a great post about this very subject.
