What is Holiness?
Holiness is a state of being Holy, to be consecrated for God. Holiness is the totality of God's Essence. It is to be set apart for God.
We should be a light to the world and conform to the standard of God and not of the world. Holiness is not measured by Dressing, Gender separation in seating and the likes.
But instead it is the Possession of clean lips, Purity in thought, a proof of love for Christ.
Holiness is reflected in our being good to others, caring attitude towards others, helping the less privileges and portraying a good picture of Jesus Christ to the world.
