Interesting thoughts, Chris and Michael! Thanks for posting!
I once heard a physician explain that our Lord was in extreme heart failure, even before He was forced to carry His cross.
Scripture tells us that when the spear pierced His side, both blood and water came out.
The fluid build-up in the pericardium (the sac around the heart) in congestive heart failure would explain that gush of both blood and water.
Here's an excellent link, well-worth the read--in Lent, or at anytime of the year---it helped me realize just a little more the immense suffering our Savior endured for us all--
(From the above link:)
Apparently to make doubly sure of death, the legionnaire drove his lance through the fifth interspace between the ribs, upward through the pericardium and into the heart. The 34th verse of the 19th chapter of the Gospel according to St. John reports: "And immediately there came out blood and water." That is, there was an escape of water fluid from the sac surrounding the heart, giving postmortem evidence that Our Lord died not the usual crucifixion death by suffocation, but of heart failure (a broken heart) due to shock and constriction of the heart by fluid in the pericardium.
Also a great site, with diagrams, too---
Amazing Love! And freely poured out--for you and for me!
'Longing to come Home, Lord, soon--- to fall at Your Feet, in worship and praise!
