Obadiah 1: 11 When they were invaded, you stood aloof, refusing to help them. Foreign invaders carried off their wealth and cast lots to divide up Jerusalem, but you acted like one of Israel’s enemies. 12 “You should not have gloated when they exiled your relatives to distant lands. You should not have rejoiced when the people of Judah suffered such misfortune. You should not have spoken arrogantly in that terrible time of trouble. 13  You should not have plundered the land of Israel when they were suffering such calamity. You should not have gloated over their destruction when they were suffering such calamity.15 “The day is near when I, the Lord, will judge all godless nations! As you have done to Israel, so it will be done to you. All your evil deeds will fall back on your own heads.

when someone has done you very wrongly.. it is our human nature to be at least relieved when not so great things happen to them... now I think we all will want to say that we don't do this.. but if we are really honest with ourselves.. these are the times when we get to saying.. "well you reap what you sow"... 

and while those words are true.. we are not to be thankful that our enemies have been destroyed... although we do this... because just like them.. we have done evil/wrong too.. in some way or another.. and trust and believe that just like theirs came back down on their head.. ours will come back down on ours.... 

it takes a very mature person to bleed when your enemy is cut.. to cry with someone who has treated you badly... to feel their sorrow with them...
