Death was inevitable for Jesus too. God Incarnate had to die because that is what humans do and further He had to come to terms not only with mortality but with the nature of His mortality. How could Our Lord identify with us if he floated away after a predetermined time, or remained with us for centuries? This Crucifixion was the only death that Our Lord could expect if He wanted to do any justice to the misery of the human condition separated from its creator. We can be sure that God understands our condition first hand, not remote on a celestial throne, but bleeding, disgraced, the victim of injustice, in unimaginable pain - all for us!
I pray thee, O Lord Jesu Christ, by that bitterness of thy Passion, which thou suffered at the hour of thy death, and then above all when thy most holy Soul passed forth from thy blessed' body; pity my soul when it is departing out of my body and bring it to everlasting life. Amen.
