The "Meism" Deception.
The selfishness of separating believers into segregational groups causes people to become obsessed with "meism" (the act of being taken up with "me" and "mine"...(people of like faith).
This internal focus on like-minded people of the same belief system renders us incapable of focusing on unlike-minded people who hold to different beliefs within the redeemed community of God.
This segregated mentality of disuniting brothers and sisters in the family of God into cliques is in direct opposition to unification within His Body, "The Church", that Christ prayed for.
This meism deceives us in believing that the work of God is in the doing of our denominational work, and our trying to protect the meism deceptional concept severely hinders us from understanding what the true work of God really is and lends to spiritual dissatisfaction.
