You adulterers and adulteresses, know you not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God. James 4:4
Its when one doesn’t hate the sinful principles and forces which drive this world, but rather, loves those principles and uses them and builds his life on them.
The principles which drive Christendom are the same which drive the world, and i detest those principles.
