2 Corinthians 7: Holiness the Missing Link

In Matthew 5:48 Jesus instructs us saying, "Be perfect, therefore as your heavenly Father is perfect." This is a call to "holiness" a reflection of God's character, showing love, mercy and righteousness without partiality, even extending this to our enemies. What happens when the Church stops operating in holiness? Apart from holiness none will see God nor experience true peace.
