Two extracts from Imagining the Kingdom

Quite simply, there is no formation without repetition. There is no habituation without being immersed in a practice over and over again… So it is precisely our allergy to repetition in worship that has undercut the counterformative power of Christian worship—because all kinds of secular liturgies shamelessly affirm the good of repetition. We’ve let the devil, so to speak, have all the repetition. And we, as liturgical animals, are only too happy to find our rhythms in such repetition. Unless Christian worship eschews the cult of novelty and embraces the good of faithful repetition, we will constantly be ceding habituation to secular liturgies.

We need stories like we need food and water: we're built for narrative, nourished by stories, not just as distractions or diversions or entertainments but because we constitute our world narratively. It is from stories that we receive our "character," and those stories in turn become part of our background, the horizons within which we constitute our world and engage in action. I cannot answer the question, what do I love? without (at least implicitly) answering the question what story do I believe? We tell ourselves stories in order to live.

Why keep swimming

Why do the majority of Christians doubt the literal existence of the Devil? We’re affected by the pervasive skepticism and disenchantment of our “secular age,” but it’s not just that we’re passively affected by our culture. A lot of us are actively searching for an intellectually honest and respectable faith, a faith that prizes scientific knowledge and literacy. From cutting-edge cosmology to genetics to evolutionary theory to particle physics to neuroscience, Christians want to investigate and enjoy the findings of science and integrate them with faith. But this pursuit, one I heartily approve of as a social scientist, can create tensions and raise hard and difficult questions: How does evolution fit with the book of Genesis? Or neuroscience with the belief in an immortal soul? The pursuit of a scientifically literate faith can move you deeper into doubt and increase the pressures of disenchantment.
Many scientifically literate Christians find it hard to believe in ghosts, and this skepticism affects their beliefs in other supernatural beings— angels, demons, and the Devil. Even belief in God is affected. Across the board in this secular age, doubt haunts belief, which is why many believers are drifting toward agnosticism and atheism. The tide of disenchantment is simply too strong, and faith is swept away. 

Consequently, a large part of being a scientifically engaged and literate Christian is swimming against this tide of doubt and disenchantment, and that’s exhausting. Some days it seems like it would just be easier to stop struggling, to let the tide of disenchantment take you and drift into unbelief. 

So why keep swimming? 

Because the secular age isn’t wholly characterized by disenchantment. Here and there in the secular, we encounter the transcendent, the holy, and the sacred. We encounter beauty and ugliness, love and meaning. We are skeptics, but we are also haunted by the sense that there is something more. 

As [Charles] Taylor describes it, the secular age is characterized by two cross-pressures. On the one hand is the downward pressure of skepticism and disenchantment, where the enchanted world is emptied out and all that is left is the flat, horizontal drama of human action and interaction. This is the trajectory of a Scooby-Doo episode, the journey to discover that, in the end, there are no ghosts or gods or devils. In the final analysis, at the end of the thirty-minute adventure, there are only human beings. 

But here and there in this secular age we also experience updrafts of transcendence, a pull toward the heavens. We’re interrupted by wonder and awe. We’re surprised by joy. We experience a deep-seated ache and yearning, a feeling of restlessness, a longing for home. Even in an age of particle physics and brain scans, we still bump into the magic from time to time, still experience the enchantment of the world. We’re skeptical and scientific people, yes, but we’re also haunted by the suspicion that the universe is more than the sum of its subatomic parts. 

Doubting and disenchanted Christians live at the center of these cross-pressures. We are skeptics, but we are also haunted in ways that agnostics or atheists are not. And that haunting keeps us swimming against the tide of disenchantment, keeps us tethered to faith through a restlessness and dissatisfaction with a thoroughly disenchanted world, a world ruled by the iron and deterministic laws of cause-and-effect.

From Reviving Old Scratch: Demons and the Devil for Doubters and the Disenchanted, by Richard Beck. 

Doubt

As far as you (and I) are concerned I have no doubt that the fear you mention is simply a temptation of the devil, an effort to keep us away from God by despair. It is often the devil working through some defect in our health, and in extreme cases it needs a medical as well as a spiritual cure. So don’t listen to these fears and doubts any more than you would to any obviously impure or uncharitable thoughts. . . . Of course, like other evil temptations, they will not be silenced at once. You will think you have got rid of them and then they will come back again—and again. But, with all our temptations of all sorts, we must just endure this. Keep on, do your duty, say your prayers, make your communions, and take no notice of the tempter. He goes away in the end. Remember I John iii, 20 “If (=though) our heart condemn us, God is greater than our heart.”

From The Collected Letters of C.S. Lewis, Volume III

The clamour of self-will

Of course I know that the Enemy also wants to detach men from themselves, but in a different way. Remember always, that He really likes the little vermin, and sets an absurd value on the distinctness of every one of them. When He talks of their losing their selves, He only means abandoning the clamour of self-will; once they have done that, He really gives them back all their personality, and boasts (I am afraid, sincerely) that when they are wholly His they will be more themselves than ever. Hence, while He is delighted to see them sacrificing even their innocent wills to His, He hates to see them drifting away from their own nature for any other reason. And we should always encourage them to do so.

From The Screwtape Letters by C S Lewis

[Note: for those unfamiliar with The Screwtape Letters, they're written by a senior devil to a junior one, giving advice on how to tempt and destroy human beings. The 'Enemy' in this case is God himself.]

The unbridled tongue

Psalm 120: 2. Deliver my soul, O Lord, from lying lips, etc. 

An unbridled tongue is "vehiculum Diaboli", the chariot of the Devil, wherein he rides in triumph. Greenhorn doth describe the tongue prettily by contraries, or diversities: "It is a little piece of flesh, small in quantity, but mighty in quality; it is soft, but slippery; it goeth lightly, but falls heavily; it strikes soft, but wounds sore; it goeth out quickly, but burns vehemently; it pierces deep, and therefore not healed speedily; it hath liberty granted easily to go forth but it will find no means easily to return home; and being once inflamed with Satan's bellows, it is like the fire of hell." 

The course of an unruly tongue is to proceed from evil to worse, to begin with foolishness, and go on with bitterness, and to end in mischief and madness. See Eccl. 10:13. The Jew's conference with our Saviour began with arguments: "We be Abraham's seed," said they, etc.; but proceeded to blasphemies: "Say we not well that thou art a Samaritan, and hast a devil?" and ended in cruelty: "Then took they up stones to cast at him." John 8:33,48,59. This also is the base disposition of a bad tongue to hate those whom it afflicts: Pr 26:28. The mischief of the tongue may further appear by the mercy of being delivered from it, for,

1. So God hath promised it (John 5:15,21). "God saves the poor from the sword, from their mouth, and from the hand of the mighty," and "thou shalt be hid from the scourge of the tongue," or from being betongued, as some render it, that is, from being, as it were, caned or cudgelled with the tongues of others. "Thou shalt hide them in the secret of thy presence from the pride of man: thou shalt keep them secretly in a pavilion from the strife of tongues" (Ps 31:20); that is, from all calumnies, reproaches, evil speakings of all kinds. God will preserve the good names of his people from the blots and bespatterings of malicious men, as kings protect their favourites against slanders and clamours.

2. So the saints have prayed for it, as David: "Deliver my soul, O Lord, from lying lips, and from a deceitful tongue."—Edward Reyner.

Quoted in Charles Spurgeon's The Treasury of David, on Psalm 120. The original material is possibly from Reyner's 'Rules for the Government of the Tongue: together with Directions in six Particular Cases,' (1656)

A literal Hell

...all these doctrines which deny submission deny God. Hell, a literal hell, is our only hope. Take it away & we will become wholly a wasteland not a half a one. Sin is a great thing as long as it's recognized. It leads a good many people to God who wouldn't get there otherwise. But cease to recognise sin, or take it away from devil as devil & and give it to devil as psychologist, and you also take it away from God. If there is no sin in this world there is no God in heaven. No heaven. There are those who have it that way. But even among the literary now it is becoming popular to believe in God. There is a certain something shocking about it.

Flannery O'Connor in A Prayer Journal, pages 26/7

Wiser

Psalm 119:98. Thou through thy commandments hast made me wiser than mine enemies. 

The commands were his book, but God was his teacher. The letter can make us knowing, but only the divine Spirit can make us wise. Wisdom is knowledge put to practical use. Wisdom comes to us through obedience: "If any man will do his will he shall know of the doctrine." We learn not only from promise, and doctrine, and sacred history, but also from precept and command; in fact, from the commandments we gather the most practical wisdom and that which enables us best to cope with our adversaries. A holy life is the highest wisdom and the surest defence. Our enemies are renowned for subtlety, from the first father of them, the old serpent, down to the last cockatrice that has been hatched from the egg; and it would be vain for us to try to be a match with them in the craft and mystery of cunning, for the children of this world are in their generation wiser than the children of light. We must go to another school and learn of a different instructor, and then by uprightness we shall baffle fraud, by simple truth we shall vanquish deep laid scheming, and by open candour we shall defeat slander. A thoroughly straightforward man, devoid of all policy, is a terrible puzzle to diplomatists; they suspect him of a subtle duplicity through which they cannot see, while he, indifferent to their suspicions, holds on the even tenor of his way, and baffles all their arts. Yes, "honesty is the best policy." He who is taught of God has a practical wisdom such as malice cannot supply to the crafty; while harmless as a dove he also exhibits more than a serpent's wisdom.

 Charles Spurgeon, writing in The Treasury of David.

Be merry!

Intriguing piece of advice from Luther...

Whenever the devil harasses you, seek the company of men or drink more, or joke and talk nonsense, or do some other merry thing. Sometimes we must drink more, sport, recreate ourselves, and even sin a little to spite the devil, so that we leave him no place for troubling our consciences with trifles. We are conquered if we try too conscientiously not to sin at all. So when the devil says to you: "do not drink," answer him: "I will drink, and right freely, just because you tell me not to."

Martin Luther
The Life and Letters of Martin Luther

Forgive without end

Never tire of forgiving, and so give the devil no hold. Be merciful and compassionate, spontaneously and wholeheartedly. The Lord forgives you all day long; in the silence of your heart, then, do the same, untiringly and sincerely.

- Pierre-Marie Delfieux, from The Jerusalem Community Rule of Life

God is our rest

If we, as the people of God, are called to be a peculiar people, learning to rest will be an important way of distinguishing ourselves from the culture of incessant labor that surrounds us. We will then point our neighbors to the God who is our rest.
