We as Christians should be mourning and not celebrating this day in America.
What are we celebrating,endemic corruption,greed,out of control violence and crime,killing babies,homosexuality as the laws of the land,the exponential attacks,sexual abuse of our children and their murder by evil forces and their revolving door justice and freedom to prey again on the weakest and most innocent,the loss of our religious freedom, the past, long gone ?
There was a day when God's people had the sense to end the celebrations and go to sack cloth and ashes.
When God sent Jeremiah with His very negative message for His people Israel, they also were in too much of a patriotic mood to heed and prepare.
Instead they attacked the messenger and called him every name in the book ,like traitor,unloving,too negative,mean spirited, etc.
They refused to believe that their very own God (of Israel) had put a bulls eye of destruction on them and their land because their hearts were full of idols, just like modern day Christian in America are full of idols.
There really is nothing new under the sun as we see history again repeating itself with God’s backslid people in their proud land full of idol's and delusion.
God NEVER changes,His people do and they always get it wrong: Ezekiel 9
