Well, God made a promise a long, long time ago-- (a long time ago!) and look what love has done: Ring it in the morning, tell it through the snow-- the promised Son of David's come! He swore it to David, He swore it by His name-- a covenant that time could never break: "Your seed will I establish, your throne forever stand, to all the generations, for My own name's sake!" Well, kingdoms rise and kingdoms fall, but the word He swore stands over all-- and here, in a manger, the promise is done: so lift up your head and behold the Son! Oh, what a Son! (what a Son!) the promised Son of David's come! Sworn from of old, and now He's here-- the highest King of all the earth! Clap your hands, let the rafters ring, lift Him high, let the whole house sing: God kept His word and heaven's begun-- oh, praise Him, praise Him, what a Son! And this little One in the hay and the cold one day will cry with a Son's own voice: "You are my God, my Father, my Rock, my stronghold, the rock of my salvation!"--O church, rejoice! Well, the One the angels bow before has come to a stable, a lowly door; Yet still He is God, and God is His own-- so run to the manger and worship the Son! Oh, what a Son! (what a Son!) the promised Son of David's come! Sworn from of old, and now He's here-- the highest King of all the earth! Clap your hands, let the rafters ring, lift Him high, let the whole house sing: God kept His word and heaven's begun-- oh, praise Him, praise Him, what a Son! I will make Him My firstborn! (Firstborn!) higher than the kings of the earth! (higher than them all!) Every crown, come lay it down-- (lay it down!) there's a greater King been born! (a greater King!) So wave your hands (wave your hands!) stomp your feet (stomp your feet!) Sing it to the mountains, sing it up and down the street: the First and the Highest, the Everlasting One-- oh, glory, hallelujah, what a Son! Oh, what a Son! (what a Son!) the promised Son of David's come! Sworn from of old, and now He's here-- the highest King of all the earth! Clap your hands, let the rafters ring, lift Him high, let the whole house sing: God kept His word and heaven's begun-- oh, praise Him, praise Him, what a Son! He's the promised One... the Son of David's come... (what a Son!) -- oh, glory... what a Son!
