ACC ~ Luke 9 v51
LIFTING UP REFERS TO PASSION, RESURRECTION AND ASCENSION
CYRIL OF ALEXANDRIA: It says, โWhen the days drew near for him to be received up, he set his face to go to Jerusalem.โ This means that after he would endure his saving passion for us, the time would come when he should ascend to heaven and dwell with God the Father, so he determined to go to Jerusalem. This is, I think, the meaning of his โset his face.โ COMMENTARY ON LUKE, HOMILY 56. [1]
