Here is an original, contemporary Christmas song by Sarah Hart that I just adore, and should be a classic. For me, right now it hits the perfect melancholy note with the future promise Christ's birth.
Oh do check out the lyrics here. Here are a couple of stanzas that just stand out for me. The third stanza:
The welcome snow each Christmastide
Falls shining from the skies
On village paths and uplands wide
All holy white, it lies
It crowns with pearl, the oaks and pines
And glitters on the thorn
But purer still the light that shines
On gladsome Christmas morn
And the sixth and last stanza:
And o’er the child a guiding star
Shall lead us into peace
And still in souls, that childlike are
His guardian love shall be
Oh then rejoice, good Christian men
Nor be of heart forlorn
For unto you, in Bethlehem
The Son of God is born
December’s darkness brings again
The light of Christmas morn.
