“What then, I ask you, is this book really? Nothing but squiggles on paper. But through the grace of God it has been used, lo these twenty years, as an instrument for human transformation.”

Here, Foster reiterates the core humility behind his work, suggesting that any book—including his own—is simply ink and paper without divine influence. By acknowledging “the grace of God” as the sustaining force, he both celebrates the book’s longevity and shifts credit away from himself and toward a higher purpose.

“Superficiality is the curse of our age. The doctrine of instant satisfaction is a primary spiritual problem. The desperate need today is not for a greater number of intelligent people, or gifted people, but for deep people.”

This quote defines Foster’s central concern: his belief that modern culture is plagued by shallowness and an obsession with quick fixes. He highlights the pressing need for depth of character, emphasizing that spiritual maturity outweighs mere intellect or talent.

“When we despair of gaining inner transformation through human powers of will and determination, we are open to a wonderful new realization: inner righteousness is a gift from God to be graciously received.”

Here, Foster underscores that external striving alone cannot address the roots of sin or spiritual emptiness. By presenting righteousness as a divine gift rather than a self-achieved goal, he shifts the focus from personal effort to humble dependence on God’s transforming grace. In doing so, he also introduces one of the many paradoxes that populate the work: the idea that despair can open the door to lasting joy.

“In contemporary society our Adversary majors in three things: noise, hurry, and crowds. If he can keep us engaged in ‘muchness’ and ‘manyness,’ he will rest satisfied.”

Foster underscores how spiritual focus is hampered by an overload of external stimuli, suggesting that busyness and overstimulation prevent meaningful communion with God. By referencing “muchness” and “manyness,” he highlights the fragmentation of attention that hinders a deeper life of reflection.

“To pray is to change. Prayer is the central avenue God uses to transform us.”

These lines concisely capture Foster’s conviction that sincere prayer inevitably leads to personal growth. By linking prayer and transformation, he underscores that engagement with God reorients the believer’s heart, resulting in ongoing spiritual renewal.

“In a culture where the landscape is dotted with shrines to the Golden Arches and an assortment of Pizza Temples, fasting seems out of place, out of step with the times.”

Foster’s imagery contrasts traditional spiritual devotion with the modern obsession with fast food and constant indulgence. His metaphor likening restaurants to “shrines” and “temples” highlights how far culture has drifted from any notion of self-denial and, with it, from genuine spirituality.

“Fasting must forever center on God. It must be God-initiated and God-ordained.”

These lines underscore that authentic biblical fasting is an act of worship rather than a human-driven display. Foster’s emphasis on divine initiative and ordination reminds readers that fasting’s true power lies in its ability to help individuals seek God’s presence and purposes above all else.

“Many Christians remain in bondage to fears and anxieties simply because they do not avail themselves of the Discipline of study.”

Foster argues that ignorance of (Christian) truth can trap people in needless worry. By emphasizing study as a remedy, he suggests that deeper understanding frees believers from destructive mental habits. Foster’s word choice—e.g., the reference to “bondage”—is in keeping with the work’s theme of Discipline as the Gateway to Freedom as well as with traditional Christian metaphors associating sin with enslavement.

“We come to the Scripture to be changed, not to amass information.”

This quote clarifies Foster’s perspective that biblical study aims at inner transformation rather than academic knowledge alone. In highlighting change as the ultimate goal, Foster reminds readers that encountering God through Scripture should alter one’s character and conduct.

“We are trapped in a maze of competing attachments. One moment we make decisions on the basis of sound reason and the next moment out of fear of what others will think of us. We have no unity or focus around which our lives are oriented.”

Here, Foster highlights how modern life lures individuals into contradictory motives, exposing the absence of a singular guiding principle. This fractured decision-making underlines the need for “inner simplicity,” a unifying focus that aligns outward choices with internal convictions.

“Freedom from anxiety is characterized by three inner attitudes: if what we have we receive as a gift, and if what we have is to be cared for by God, and if what we have is available to others, then we will possess freedom from anxiety.”

This passage underscores the heart posture of simplicity, identifying and clearly enumerating key attitudes that break the grip of material worry. By recognizing God’s ultimate ownership and resisting the urge to hoard, believers experience a peaceful confidence that overcomes consumer-driven fear.

“Loneliness is inner emptiness. Solitude is inner fulfillment.”

In this concise contrast, Foster distinguishes two seemingly similar states by highlighting their opposite natures: Loneliness deprives, whereas solitude replenishes. The language underscores his view that the real focus of solitude is not absence but a quiet wholeness that one carries internally.

“Submission is the ability to lay down the terrible burden of always needing to get our own way.”

Foster crystallizes the essence of biblical submission as a liberating rather than oppressive force. By framing self-will as a burden, he underscores how yielding one’s personal demands brings relief and opens space for genuine love in relationships.

“Self-denial is simply a way of coming to understand that we do not have to have our own way. Our happiness is not dependent upon getting what we want.”

These lines clarify how submission is inextricably linked to laying aside what Foster suggests is a compulsive need (exacerbated by modern consumerism) for self-gratification. Foster presents self-denial not as a harsh call to self-hatred but as the discovery that true contentment rests on putting others first.

“Service banishes us to the mundane, the ordinary, the trivial.”

Foster stresses that genuine service often unfolds in everyday tasks that lack glamorous appeal, contrasting sharply with a culture that values prestige. The phrase “banishes us” acknowledges that true servanthood can feel like exile from the grand or heroic, yet Foster contends that it is precisely in these small, humble actions that loving character is forged.

“When we choose to be a servant, we give up the right to be in charge. There is great freedom in this.”

These lines highlight Foster’s central theme: that by relinquishing control, one experiences liberation instead of loss. The paradox is that surrendering the demand to lead or assert one’s will frees believers to serve others wholeheartedly and discover deeper joy in relationships.

“We are sinners together. In acts of mutual confession we release the power that heals. Our humanity is no longer denied, but transformed.”

Here, Foster underscores the communal nature of confession, insisting that Christians must acknowledge their shared brokenness. The phrase “sinners together” contrasts with the notion of moral isolation, while “release the power that heals” highlights the transformative effect collective honesty brings.

“It is often helpful by prayer to set the cross between yourself and the penitent. Everything is filtered through the light of the cross.”

Foster’s imagery of placing the cross between confessor and confessant illustrates the need for Christ’s mediation in human interactions. By viewing each other “through the light of the cross,” believers keep compassion central and avoid mere human judgment, thus preserving the sacredness of the confession experience.

“Worship is the human response to the divine initiative.”

Foster crystallizes that worship is not primarily human-driven but arises from God’s invitation. By calling it a “response,” he underscores how grace precedes any effort to honor God, ensuring that worship is about divine engagement rather than mere human ceremony.

“Just as worship begins in holy expectancy, it ends in holy obedience.”

These words relate to Foster’s key idea that genuine adoration must produce tangible change—a variation on the theme of Blending Inner and Outward Expressions of Faith. The phrase “holy expectancy” shows believers entering worship with hopeful anticipation, while “holy obedience” anchors the service’s conclusion in practical follow-through, ensuring worship shapes daily living.

“In our day heaven and earth are on tiptoe waiting for the emergence of a Spirit-led, Spirit-intoxicated, Spirit-empowered people.”

Foster’s imagery of “heaven and earth on tiptoe” underscores the sense of anticipation for a renewed Christian community. By describing believers as “Spirit-led, Spirit-intoxicated, Spirit-empowered,” he conjures a vision of followers invigorated by the Holy Spirit for transformative witness.

“They had dared to live on the basis of Spirit-rule; no fifty-one percent vote, no compromises, but Spirit-directed unity. And it worked.”

Here, Foster highlights the early church’s departure from human-made systems like majority rule, choosing instead a “Spirit-directed unity” that transcends typical decision-making. The triumphant tone of “and it worked” conveys both the practicality and power of living under divine guidance.

“Celebration is at the heart of the way of Christ. He entered the world on a high note of jubilation […] He left the world bequeathing his joy to the disciples.”

This passage establishes how integral joy is to Jesus’s entire ministry. By highlighting both inception and conclusion, Foster underscores that joy is central, not incidental, to Christian spirituality.
