Do you have scriptural proof of that?1 Corinthians 5:11-13 <- is the definition of being a friend of the world.
I think even the world wants peace. Do you agree? How is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler being friendly?
By the way, which am I? Am I "immoral" because I dedicated myself to God, discovered that God cannot be found in your organization and I left?
Friend: a person whom one knows and with whom one has a bond of mutual affection, typically exclusive of sexual or family relations.
