Vs.19 for sure, but vs.14 is a deep spiritual truth,Also, v.14 and v.19 also make it clear that Christ died for everyone.
For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead: vs.14
He's showing why he and all people should consider ourselves dead, because our Savior did, because of his love of mankind. Jesus truly lived as any man, though without sin as any man.
I think one of the most insightful stories into Gods' character is where the woman was caught in adultry. The only One who had a right to cast a stone didn't. Amazing!
