PDF Summary:Prayer, by Timothy Keller

Prayer is fundamental to the Christian faith, yet many people struggle to develop a consistent and meaningful prayer practice. In Prayer, Timothy Keller explores the theological foundations of prayer and its transformative effects on believers. He explains that prayer is a response to God's word in Scripture and describes it as a two-way conversation that deepens our relationship with God.

Keller examines various approaches to prayer throughout Christian history, from medieval practices to modern evangelical methods. He discusses how to engage in Scripture-shaped prayer and explains the core elements of communion with God. Throughout, Keller emphasizes that effective prayer combines both intellectual understanding and experiential connection with God, ultimately transforming our hearts and perspectives on life.

(Shortform note: In How God Changes Your Brain, neuroscientist Andrew Newberg and therapist Mark Robert Waldman explain that intensely analytical, language-based approaches to religion—such as dissecting sacred texts, categorizing doctrines, and concentrating on logical or literary analysis—primarily activate the brain’s left-hemisphere language centers and prefrontal executive networks. This reduces engagement of the limbic and parietal regions that are associated with awe, self-transcendence, and a felt sense of relational connection with God. Consequently, the religious life becomes more conceptual and propositional and less emotionally immersive or experientially vivid.)

This method of study, which takes practice, aimed more at interpreting the text than at meditation and experience of God. Following this sort of study, people would pray, yet this intellectual approach didn’t organically lead to worship. Instead, the focus of prayer became requesting what was needed and admitting sins. Keller explains that many felt that the customary evangelical time of quiet devotion was overly rational. To enhance their connection with the divine, numerous Protestants have embraced practices that align more with Catholic and Eastern Orthodox customs, like lectio divina, contemplative prayer, and set times for liturgical prayer.

(Shortform note: Not all Protestants are happy about this turn toward lectio divina, contemplative prayer, and fixed hours of liturgical prayer. In A Time of Departing, Ray Yungen argues that contemplative prayer and related practices such as lectio divina are not harmless devotional aids but a spiritually dangerous form of “Christianized” mysticism, derived from Roman Catholic and Eastern religious sources, that conditions people to use mantra-like repetition and enter altered states of consciousness in which biblical discernment is suspended, thereby opening the door for New Age, panentheistic, and occult influences to infiltrate the church under the guise of a deeper, more intimate experience of God.)

Phyllis Tickle's volumes, The Divine Hours, are among the most successful modern adaptations of ancient practices of praying at designated times. Tickle conveniently compiles brief selections of Psalms, Scripture, hymn stanzas, ascriptions, and prayers on a single page, making them more accessible than traditional Divine Office guides. Yet, she doesn't incorporate certain daily prayer developments from Cranmer and Protestantism. She recommends praying three or four times a day instead of twice, and she departs from the ordered, sequential reading of Scripture linked to Reformation-era figures like Cranmer and Calvin. Keller notes that Tickle's promotion of written prayers doesn't contradict Reformation practice.

(Shortform note: Keller’s comparison of The Divine Hours with Cranmer’s Reformation-era daily prayer practices assumes a broader historical and theological context. Cranmer’s daily offices were designed to guide worshipers through most of the Bible in a year, while The Divine Hours offers a more selective, theme-based approach. This reflects a longstanding tension in Christian liturgical practice between comprehensive scriptural engagement and focused devotional reading. Cranmer’s approach, influenced by the Reformation emphasis on sola scriptura, sought to immerse believers in the full breadth of Scripture, while Tickle’s method prioritizes accessibility and thematic coherence.)

While certain non-Anglican clergy like John Bunyan were staunchly against any pre-composed prayers, others of Bunyan's time, like John Owen, considered structured prayers to be beneficial if they were composed by devout "people from their own experience and the light of Scripture." These prayers can affect us emotionally and inspire and guide us personally in prayer.

(Shortform note: The contrasting views of Bunyan and Owen on pre-composed prayers reflect the religious and political tensions of seventeenth-century England. The Book of Common Prayer, which Bunyan opposed, was seen by many dissenters as a tool of political control rather than a neutral devotional aid. This historical context helps explain why some, like Bunyan, rejected pre-composed prayers entirely, while others, like Owen, could affirm structured prayers when they arose from genuine spiritual experience.)

Next, we will examine methods for engaging in Scripture-shaped communication with God and the core elements and dynamics of connecting with God.

Methods for Scripture-Shaped Prayer

Keller explains that meditating on the Bible involves deep contemplation and application of biblical truths. He describes it as the process of taking a biblical principle and embedding it in your heart so it transforms you.

(Shortform note: To embed a biblical principle in your heart, choose a short verse that encapsulates the principle and memorize it. Then, recall it from memory several times a day for a week.)

Now, we will consider scriptural forms and structures for prayer.

Scriptural Forms and Structures for Praying

Keller explains that the Our Father provides a structure for us to pray. It distills other prayers and provides vital advice on what to emphasize and the topics to cover, along with intent and attitude.

(Shortform note: The Our Father has been a central prayer for Christians since the earliest days of the church. The Didache, a first-century Christian text, instructed believers to recite the Our Father three times a day, using it as a pattern for all their prayers.)

The Core Elements & Dynamics of Fellowship With God

Keller asserts that prayer involves both being in union with God and pursuing His kingdom. He describes prayer as both communing with God and an experience of Him. The conventional ways of praying—praising, confessing, giving thanks, and asking for help—are tangible activities and also deeply meaningful experiences. We need to understand the wonder of glorifying him, the closeness of discovering the grace he gives, and the challenge of seeking his assistance, all of which can reveal the spiritual truth of his presence to us. Prayer is therefore both awe-inspiring and intimate, both a struggle and reality. These may not occur in every prayer, but they should be central aspects throughout our lifetime of prayer.

Spiritual Dryness and Depression

Keller’s description of prayer as “awe-inspiring and intimate” and marked by “the wonder of glorifying him” and “the closeness of discovering the grace he gives” may not resonate with people who experience long-term spiritual dryness. This is especially true for those who experience clinical depression, which can cause a sense of spiritual emptiness and a lack of connection to God. For these individuals, prayer may feel more like a struggle than a source of comfort or inspiration. This can lead to feelings of guilt or inadequacy, as they may believe that their lack of spiritual connection is a sign of weak faith.

Next, we will discuss prayer as speaking with God in a way that deepens our relationship with Him.

Elements of a Connection With God

Keller describes prayer as an interaction with God that deepens our relationship with Him. It replies to God’s words and grace, allowing us to experience a complete meeting with Him. He explains that as our connection with God grows stronger, our prayers become more powerful. Prayer is a two-way conversation. We listen to what God says and reply with prayer. God's words are one and the same as His actions, and they have the power to create and transform.

Keller believes our prayers should reflect God's nature as our companion, parent, beloved, caretaker, and sovereign. We should use a variety of words and emotions in our prayers, just like the Psalms. Furthermore, we shouldn't base our prayers on what we desire to feel or experience. Instead, we should pray in response to God's nature.

The Dangers of Treating Prayer as a Two-Way Conversation

Keller’s description of prayer as a “two-way conversation” in which “we listen to what God says” may be problematic for some people. For example, people with mental illnesses such as schizophrenia may mistake their own inner voices for God’s words. This could lead to them making poor decisions based on what they believe God is telling them to do. Even people without mental illnesses may struggle to distinguish between their own thoughts and God’s words. For example, someone who’s struggling with a difficult decision may convince themselves that God is telling them to choose the option they already wanted to choose. This could lead to them making a decision that isn’t in their best interest.
