Holiness consists in conformity to God. Holiness is 
  the sparkling of the Divine nature. What makes the seraphim angels of 
  light — but their holiness? Holy men shall be "equal with the angels."
As the diamond is to the ring — so is holiness to the 
  soul. Those who oppose it, cannot but admire it.
Holiness leads to Heaven — it is the King's highway to Heaven. "A highway shall be there, and it shall be called the way of holiness." Holiness is glory militant — and happiness holiness triumphant.
Be among the spices, and you will smell of them. 
  Association induces assimilation. Communion of saints, promotes the 
  holiness of saints.
Holiness is the beauty of the soul; it makes us like 
  God and angels. As the sun is to the world — so is holiness to the soul.
The foundation of piety is on the heart; yet its 
  beautiful frontispiece appears in the conversation. An upright Christian 
  is like Solomon's temple — gold within and without. Piety is like 
  leaven, which amalgamates and mingles itself with the whole man.
Walk closely with God every day. Live as under the 
  continual inspection of God's omniscient eye — live holily. Peace and 
  purity must walk together. The way to preserve our peace is to preserve 
  our integrity. Turn your closets into temples. 
Search the Scriptures: the two Testaments are the two 
  lips by which God speaks to his people, "Great peace have those who love 
  Your law."
Holiness is God's stamp and impress; he will not own 
  any who are without it. Holiness fits for communion with God. The holy 
  mind enjoys the presence of God, and when God sees his likeness there, 
  he gives his love.
To be learned and ungodly, is like Satan transformed 
  into an angel of light. 
To be beautiful and ungodly, is like a splendid 
  picture hung up in an infected room. 
Only godliness can ennoble, beautify, and adorn the 
  man, and command the admiration of angels and of God.
Holiness is our spiritual beauty. Godliness is to the 
  soul, as the light is to the world, to illustrate and to adorn it. Man 
  is eminent before God, not for his greatness — but for his holiness. 
  Hence a godly man walks with God, "Our fellowship is with the Father" — 
  this is dignified elevation. A dwarf cannot walk among the stars, nor 
  can a dwarfish soul have communion with Heaven. 
What is the beauty of the angels, but their purity? 
  Their distinguished title is, "The Holy Angels;" and a soul furnished 
  with godliness is damasked with beauty, and is enameled with purity. 
  This is "the clothing of wrought gold" with which the King's daughter 
  (the Church) is attired, and which makes her resemble "the wings of a 
  dove covered with silver, and her feathers with yellow gold."
Purity of heart gives forth, although faintly, some 
  idea and representation of God. There is no likeness to God will prove 
  so blissful, as our being like him in purity. God loves the pure in 
  heart. Love is founded on likeness.
  
Holiness is glory in the seed — and glory 
  is holiness in the flower.
