Theology Course in a Christmas Carol

I've been meditating on the words to one of the best loved Christmas hymns: Charles Wesley's "Hark, The Herald Angels Sing." There is an entire course in Biblical Theology, a summary of Bible truth, in the words to this Carol.

Hark, the herald-angels sing
glory to the new-born King,
peace on earth, and mercy mild,
God and sinners reconciled.
Joyful, all ye nations, rise,
join the triumph of the skies;
with the angelic host proclaim,
'Christ is born in Bethlehem.'
Hark, the herald-angels sing
glory to the new-born King.

Christ, by highest heaven adored,
Christ, the everlasting Lord,
late in time behold him come,
offspring of a Virgin's womb.
Veiled in flesh the Godhead see:
hail, the incarnate Deity,
pleased as man with man to dwell,
Jesus, our Emmanuel.
Hark, the herald-angels sing
glory to the new-born King.

Hail, the heaven-born Prince of Peace:
hail, the Sun of Righteousness.
Light and life to all he brings,
risen with healing in his wings.
Mild he lays his glory by,
born that man no more may die,
born to raise the sons of earth,
born to give them second birth.
Hark, the herald-angels sing
glory to the new-born King.

Come, Desire of nations, come,
fix in us thy humble home;
rise, the woman's conquering seed,
bruise in us the serpent's head;
now display thy saving power,
ruined nature now restore,
now in mystic union join
thine to ours and ours to thine.
Hark, the herald-angels sing
glory to the new-born King.

How many Gospel doctrines can you find in these words? I'll give my summary tomorrow.
