Was having a Bible Study and looking at Christmas Hymns as well. In so doing, I noticed something special (to me) in the chorus of We Three Kings: The end of the chorus says:
"Guide us to thy Perfect Light"
What struck me was that sometimes I hear people singing "guide us with thy perfect light" but that is not what the words actually are. Then I realized that "thy perfect light" may well be refering to Jesus Himself!
Full chorus says:
O Star of wonder, star of night
Star with royal beauty bright
Westward leading, still proceeding
Guide us to Thy perfect light
I just think it may be wonderful IF "thy perfect light" is actually speaking of Jesus.
