The term comes from the military which basically means that the people firing and killing are on the same side as the killed.
I don't know about you all but I am so tired of hearing about God's kids falling to "Friendly Fire". Christian tearing down fellow Christians, for what? The Bible tells us to be each other’s keepers, It tells us to be stepping stones not stumbling blocks, It tells us that we are to be Christ like not act like a pack of devils to each other.
I think (personal opinion) we as Christians need to get our heads out of rectal seclusion and get it in "The Game". There are real people going to hell cause we are so busy tearing down the ones that are already saved, sanctified, and forgiven that we are not focused on the people God is telling us to minister too. I heard too many things of this nature happening in "The House" to just sit here and watch it happen anymore. "United We Stand, Divided We Fall". Do not allow the enemy to ensnare you into being divided. Resist the temptations of Gossip and back biting. Watch your actions that you don't cause your brother or sister to stumble. Love, Love, Love as Christ loves you. ALL of us have sinned and fallen short of the glory of God, we all have mud and dirt and blemishes we are not proud of. The past is the past. Forgiven by God and is what it is….the past. Fellow Christians today is the day where we stop looking at what we did, or what someone else did and we move forward sharing the Love of Christ with those in need of a God just like we all needed a God before we were introduced to our God.
Easter is this weekend and a perfect time to get those in need to “The House” so that they can meet The One that is ready to heal their wounds.
