Hello ,
A few years ago, back in 1990, the USA was involved in what was known as the Persian Gulf War. Troops took on the Iraqi forces out in the desert of Kuwait. In those two months, January and February, the USA won an outstanding victory, and had relatively few casualties.
One of the interesting things about that war was that a number of our troops weren't injured or killed by the enemy. They were the victims of what is called "friendly fire," from artillery.
Friendly fire is where you are hit by ammunition by your own troops. In other words, it's where your own soldiers become your worst enemy. You can't prepare for it, and you never see it coming.
Is it possible that sometimes Christians are the victims of "friendly fire" from those who call themselves "family?" What would our world be like if they saw Christians for what they claim to be, rather than what they often are? Check out these verses found in the Gospel of John, chapter 13. Scripture
Have a great day and God bless!
