It’s a mistake to think a friendship is forming simply because you fight the same enemy. Just because So-And-So’s enemy is also your enemy doesn’t mean So-And-So is now your friend, unless you’re Pontius Pilate (Luke 23:12). An alliance is not a friendship by definition. Allies band together for mutual benefit, while friends unite around mutual affection for each other. There’s a mammoth difference between two people who need each other for selfish reasons and two people who love each other for no reason at all but for Christ’s sake.
Greater love has no one than this, that someone lay down his life for his friends.
– John 15:13
Friends are allies, but not all allies are friends. When it comes to loyalty, rubber meets the road when there’s no more personal gain to be had. What happens when a common enemy is defeated or a mutual goal is achieved? Will steadfast love sustain the relationship or will the union dissolve for lack of shared goals? Or maybe that goal isn’t achieved yet but your ally no longer needs you to accomplish it.
Some friendship that is!
Don’t be seduced into a temporary “friendship” where fighting mutual enemies undergirds the relationship – especially if you were recently enemies. Don’t be suckered into the “we both want the same thing” trap. Enemies can become your trusted friends, but it’s gotta be legitly free of selfishness.
