I have Wesley's original in front of me, so I'll save you the trouble.

Lyr. Add: HARK HOW ALL THE WELKIN RINGS
Charles Wesley, 1739

Hark how all the welkin rings,
Glory to the King of kings;
Peace on earth and mercy mild,
God and sinners reconciled.

Joyful all ye nations rise,
Join the triumph of the skies;
Universal Nature say,
"Christ the Lord is born today.

Christ by highest heaven ador'd,
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 men appear,
Jesus! Our Immanuel here!

Hail, the heavenly Prince of Peace!
Hail, the Sun of Righteousness!
Light and life to all he brings,
Risen with healing in his wings.

Mild he lies His glory by,
Born that man no more may die,
Born to raise the sons of earth:
Born to give them second birth.

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.

Adam's likeness, Lord efface;
Stamp thy image in its place.
Second Adam from above
Reinstate us in thy love.

Let us thee, though lost, regain
Thee, the life, the inner Man:
O! to all thyself impart,
Form'd in each believing heart.
