In Bethlehem, the lowly,
A Child to us is born,
The Son of God incarnate,
This blessèd Christmas morn,
Surely, surely,
And I will be His own.
And while in awe I ponder
Thy mystery divine,
My heart is lost in wonder
That Christ is also mine
Surely, surely,
And Christ is also mine.
O dearest Child, how can I
Repay Thy wondrous love
In which Thou com’st to save me
From Thy great throne above?
Surely, surely,
From Thy great throne above.
My life, my all, I bring Thee;
Oh, grant me, I implore,
Thy grace to serve and love Thee
Now and forevermore.
Surely, surely,
Now and forevermore.
