Are these the words you are looking for?
I transcribed them from this youtube:

The Scarlet Thread
His precious blood was freely shed for us
the Son of God, the Son of Man
our cross he bore scorned by humanity
He suffered pain enduring agony
chorus
A scarlet thread is woven through all time
a Promise kept the Covenant of Christ
A crimson red redeeming tie that binds
the scarlet thread of holy sacrifice
Of death grave He bodly rose above
renewing hope redeaming Blood
The crown of thorns replaced by majesty
to offer life for all eternity
chorus
A scarlet thread is woven through all time
a Promise kept the Covenant of Christ
A crimson red redeeming tie that binds
the scarlet thread of holy sacrifice
