Holiness is consecrated closeness to God. Holiness is in essence obeying God, living to God and for God... taking His side against sin... loving and serving God out of reverence for Christ."

(J.J. Packer).  

"Do not forget the culture of the inner man - I mean of the heart. How diligently the Calvary officer keeps his sabre clean and sharp.; every stain he rubs off with the greatest care. Remember you are God's sword - His instrument... it is not great talent. God blesses so much as great likeness to Jesus. A holy minister is an awesome weapon in the hands of God." (Robert Murray McCheyne).

"Holiness is a flower that grows not in Nature's garden. Men are not born hopeless in their heart, as they are born with tongues in their mouths; holiness is of Divine offspring; it is a pearl of great price that is to be found in no nature but a renewed nature, in no bosom but a satisfied bosom." (Thomas Brooks)

"Holiness is what you are in the dark. It takes you into the holy place: where you breathe the oxygen of heaven and when you are scared to sin. Holiness is making sure that God is comfortable in my life." (Alex Buchanan)  

"Say not that thou hast royal blood in thy vein and art born of God, expect thou canst prove thy pedigree by daring to be holy." (William Gurnall, Puritan Writer and Pastor)  

"We have no access to the holy place until we have confronted the unholy places in our own lives." (M. Stibbe)  

Holiness and Sanctification  

A sculptor was asked how he could carve a lion's head out of a large block of marble. I just chip away everything that doesn't look like a lion's head", he replied. God works on our being and chips away everything that doesn't look like Christ.
