cardiac a-rest

so we have been studying cardiac contractility in h phys, and today we learned that the system of venous return coupled with the contained electrical activity of the heart makes its integrity for conserved function amazingly resilient!...in other words, God made our hearts nearly unbreakable ;o)...as much as i might think that it is impossible to remidiate the past, i suppose that by God's incredible grace we can allow Him to prove Himself more faithful than our will might suppose. in my human, feeble mind i find myself so doubtful of the veracity of one's heart -- but what do i really know? (matthew 19:26)
