On Holiness

1 Peter 1:16 NIV
for it is written: "Be holy, because I am holy."

Many a times in the Bible prophets and Jesus say we are to be Holy. We are to be Holy not because to make God Holy, he is Holy and hence he says, "Be holy, because I am Holy".

Ephesians 1:4 NIV

For he chose us in him before the creation of the world to be holy and blameless in his sight. In love

Christ is the Head of the Church, as he is the Leader. He expects the Church, i.e. he expects us to be Holy.

Ephesians 5:25-27New International Version (NIV)

25 Husbands, love your wives, just as Christ loved the church and gave himself up for her26 to make her holy, cleansing[a] her by the washing with water through the word, 27 and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless.

We need to be careful with Holiness.

Matthew 7:6New Living Translation (NLT)

6 “Don’t waste what is holy on people who are unholy. Don’t throw your pearls to pigs! They will trample the pearls, then turn and attack you.

Psalm 99 English Standard Version (ESV)

The Lord Our God Is Holy

99 The Lord reigns; let the peoples tremble!
    He sits enthroned upon the cherubim; let the earth quake!
2 The Lord is great in Zion;
    he is exalted over all the peoples.
3 Let them praise your great and awesome name!
    Holy is he!
4 The King in his might loves justice.[a]
    You have established equity;
you have executed justice
    and righteousness in Jacob.
5 Exalt the Lord our God;
    worship at his footstool!
    Holy is he!

6 Moses and Aaron were among his priests,
    Samuel also was among those who called upon his name.
    They called to the Lord, and he answered them.
7 In the pillar of the cloud he spoke to them;
    they kept his testimonies
    and the statute that he gave them.

8 O Lord our God, you answered them;
    you were a forgiving God to them,
    but an avenger of their wrongdoings.
9 Exalt the Lord our God,
    and worship at his holy mountain;
    for the Lord our God is holy!

Isaiah 6:3 NIV

And they were calling to one another: "Holy, holy, holy is the LORD Almighty; the whole earth is full of his glory."
