A relatively modern hymn, sung congregationally (messy, beautiful, and full of joy). This is probably my favorite Advent Hymn, mostly because of the lyrics (below).
Awake! Awake, and Greet the New Morn
Music and Lyrics by Marty Haugen
Awake! Awake, and greet the new morn, for angels herald its dawning.
Sing out your joy, for soon he is born, behold! the Child of our longing.
Come as a baby weak and poor, to bring all hearts together,
he opens wide the heavenly door and lives now inside us forever.
To us, to all in sorrow and fear, Emmanuel comes a’singing,
His humble song is quiet and near, yet fills the earth with its ringing,
music to heal the broken soul and hymns of loving kindness,
the thunder of his anthems roll to shatter all hatred and blindness.
In darkest night his coming shall be, when all the world is despairing,
as morning light so quiet and free, so warm and gentle and caring.
Then shall the mute break forth in song, the lame shall leap in wonder,
the weak be raised above the strong, and weapons be broken asunder.
Rejoice, rejoice, take heart in the night, though dark the winter and cheerless
the rising sun shall crown you with light, be strong and loving and fearless.
Love be our song and love our prayer and love our endless story;
May God fill every day we share and bring us at last into glory.
