The reason there are “christians” that act like something in the cast of “Mean Girls” is that Christianity is a spiritually imparted thing, not a learned thing, not a church you join, not something you inherit from your parents, and not a lofty goal to achieve- by continually striving to get there. “Real” Christianity is receiving by God’s spirit His ways, his revelations, his fruits of the Spirit, and most of all; HIS kind of Love. The types who think they have it (and have just learned to use the bible to hurt people) are the types that will kick a new Christian when they are down, so watch out! Don’t be deceived either, into thinking these false representatives of Christ are a true picture of “who he is.” Their image may say christian while their actions continually display behavior of the evil one.
“The acts of the flesh are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.” Gal 5:19-21
