Far and wide we are reviving to see, as the fathers of our faith saw before us, that whatever else holiness is, it is a sacred and binding debt. It is not an ambition; it is a duty. We are bound, every one of us who names the name of Christ, to be holy, to be separate from evil, to walk by the Spirit...Holiness is beauty. But it is first duty, practical and present, in Jesus Christ.

Sin to a believer is horrible, because it crucified the Saviour; he sees in every iniquity the nails and spear.

If Christ seldom makes offers without demands, He also seldom makes demands without offers. He offers His strength to enable us to meet His demands. What Christ Thinks of the Church: An Exposition of Revelation 1 - 3 (Grand Rapids, Baker: 2003) 43

It is a great deal better to live a holy life than to talk about it. Lighthouses do not ring bells and fire cannon to call attention to their shining - they just shine.

Holiness consisteth not in a cowl or in a garment of gray. When God purifies the heart by faith, the market is sacred as well as the sanctuary; neither remaineth there any work or place which is profane.

A true Christian is one who has not only peace of conscience, but war within.

Let me burn out for God.

Sound protestant and evangelical doctrine is useless if it is not accompanied by a holy life. It is worse than useless: it does positive harm. It is despised by keen sighted and shrewd men of the world, as an unreal and hollow thing, and brings religion into contempt.

Assurance of salvation is a precious thing, so precious and so necessary that we dare not dilute it with feelings of safety apart from transformed lives. A Godward Life, 255

To be sound in faith and holy in life - this is the kernel of Christiantiy.

God has one destined end for mankind - holiness! His one aim is the production of saints. God is not an eternal blessing- machine for men. He did not come to save men out of pity. He came to save men because He had created them to be holy.

So remember, you who profess to be followers of the Lord Jesus, that to you indifference is impossible! You must bless the church and the world by your holiness, or you will curse them both by your hypocrisy and inconsistency. In the visible church it is most true that "no man liveth unto himself, and no man dieth unto himself."

The man who has nothing more than a kind of Sunday religion -- whose Christianity is like his Sunday clothes put on once a week, and then laid aside -- such a man cannot, of course, be expected to care about growth in grace.

God didn't save you to make you happy. That's a by-product. He saved you to make you holy. You were predestinated to be conformed to the image of God's Son.

Holiness appeared to me to be of a sweet, pleasant, charming, serene, calm nature; which brought an inexpressible purity, brightness, peacefulness, and ravishment to the soul. In other words, that it made the soul like a field or garden of God, with all manner of pleasant flowers.

There is no true holiness without humility.

Christianity is a battle - not a dream.

Let it not be imagined that the life of a good Christian must be a life of melancholy and gloominess; for he only resigns some pleasures to enjoy others infinitely better.

Doctrine is the framework of life - the skeleton of truth, to be clothed and rounded out by the living grace of a holy life.

Wherever the fear of God rules in the heart, it will appear both in works of charity and piety, and neither will excuse us from the other.

Our peace and confidence are to be found not in our empirical holiness, not in our progress toward perfection, but in the alien righteousness of Jesus Christ that covers our sinfulness and alone makes us acceptable before a holy God.

The nature of Christ's salvation is woefully misrepresented by the present-day evangelist. He announces a Savior from hell rather than a Savior from sin. And that is why so many are fatally deceived, for there are multitudes who wish to escape the Lake of Fire who have no desire to be delivered from their carnality and worldliness.

How little people know who think that holiness is dull. When one meets the real thing it is irresistible.

The first priority of my life is to be holy, and the second goal of my life is to be a scholar.

Everybody thinks of changing humanity, but nobody thinks of changing himself.

The countries far north are cold and frozen, because they are distant from the sun. What makes such frozen, uncomfortable Christians, but their living so far from heaven? And what makes others so warm in comforts, but their living higher, and having nearer access to God?
