Whitney lays out a case for the importance of spiritual disciplines in the Christian life. He begins with a fictional anecdote about a boy frustrated with how difficult it is to learn the guitar. This boy has an inspirational vision of a beautiful performance by a guitar virtuoso and then later discovers that the vision was of himself, having grown and become a master of the guitar some years later. The implication is that it is long, patient practice that leads to the mastery of a skill. Whitney suggests that what the boy really needed was the inspiration necessary to make his practices meaningful, rather than simply tiresome: “Discipline without direction is drudgery” (1). In the same way, Christians may find it helpful to catch a glimpse of why they should take up disciplines. For Whitney, the answer is godliness; Scripture commands Christians to undertake spiritual disciplines so that they may grow in character and virtue, becoming more like Christ and reflecting more of God’s own moral character. He centers Spiritual Disciplines for the Christian Life on the biblical command of 1 Timothy 4:7, “Discipline yourself for the purpose of godliness” (4), with the final five words—for the purpose of godliness—providing the tagline for every chapter title in the book.

Whitney draws examples from church history, noting that all of the great men and women of the Christian faith were people of discipline who intentionally fostered habits of prayer, Bible reading, fasting, and so on. He draws on examples from Scripture, pointing out the Gospel of Luke’s stories of Zacchaeus and Bartimaeus, both of whom took desperate measures to place themselves in Jesus’s path. This is what the spiritual disciplines do: They have no magical power in and of themselves, but they put people in the right condition to receive God’s work in their lives.

Further, the Bible is very clear that these disciplines are expected parts of the Christian life, not an optional add-on. There are dangers involved in choosing to forego them because one is also foregoing the growth in grace that is necessary for Christian maturity. The best decision, then, is to undertake the disciplines as a joyful provision of God’s grace in one’s life and to keep the promise of godliness always in view.

Whitney begins laying out the core spiritual disciplines, beginning with Bible intake (the subject of both Chapters 2 and 3). He recalls a trip he took to East Africa, where he was shocked by the low levels of doctrinal understanding and Christian practice among believers, which he attributed to lack of access to the Bible. Knowing and applying the lessons of the Bible to one’s life is foundational to being a Christian: “No Spiritual Discipline is more important than the intake of God’s Word. Nothing can substitute for it. There simply is no healthy Christian life apart from a diet of the milk and meat of Scripture” (22).

Whitney examines three main means of Bible intake in the Christian life: hearing the Word, reading the Word, and studying the Word. The first of these—to gather with other Christians to hear the Bible read and expounded—is often overlooked by modern Christians but regularly assumed and commanded in Scripture. To those who insist that being a Christian does not mean that one must go to church regularly, Whitney marshals scriptural evidence to show that communal spiritual learning was a basic biblical assumption of how the Christian life should operate. The practice of hearing the Word can extend beyond church, however, to include Christian teaching by radio, television, and other media. 

When it comes to reading the Bible, Whitney underscores the necessity of daily practice, likening it to the requirements to eat and to breathe. To that end, he offers three practical suggestions. The first is to intentionally set aside time to read the Bible each day. Although the Bible is dauntingly long, just 15 minutes a day can see it completed in a year. Second, Christians should choose a Bible reading plan. There are many plans available, all of which divide up the readings with consistency and variety in mind, and sticking to an ordered plan can help add motivation to one’s intentionality. Third, it’s helpful to find a portion of the day’s reading to meditate on, retaining it in one’s memory and prayerfully considering it in a slow and thoughtful way. As regards studying the Bible, Whitney counsels Christians to engage seriously and thoughtfully with the text, not only reading but seeking to learn the underlying logic and lessons of the biblical texts.

This chapter continues Whitney’s focus on Bible intake. He centers his reflections on three further ways of receiving and processing biblical content: memorizing the Word, meditating on the Word, and applying the Word. With regard to memorization, he encourages readers to commit to a regular program of setting Bible verses to memory, making use of an established program if possible. He also includes several practical suggestions, such as incorporating regular review times and employing pictorial associations as mnemonic reminders. Besides being counseled by Scripture itself, memorization bears innumerable fruits for the Christian life: “Memorizing Scripture strengthens your faith because it repeatedly reinforces the truth, often just when you need to hear it again” (40). The mind is able to draw on that content whenever needed—for encouragement and wisdom, or for an apt word when evangelizing or when counseling another person.

Meditation is likewise a valuable practice for the Christian. To meditate on Scripture is to select a passage and work over it slowly and intentionally, prayerfully considering all its dimensions. Whitney draws on Psalm 1, where the text paints a picture of a righteous man flourishing because he spends time meditating on God’s Word. Meditating can be done by praying through the words of the text, by studying the passage for its main meaning and application, and by emphasizing different words in the verses to see what new insights might emerge. For implementation, Whitney sketches out 17 separate methods of meditation that the reader can employ.

Meditation is closely linked to Whitney’s final method of Bible intake, which is applying God’s Word. Christians read and study the Bible not just to understand it, but to put its teachings in action in their own daily lives: “Our problem continues to be more a lack of action than comprehension. The words of Scripture must be understood to be applied, but until we apply them, we don’t really understand them” (73). Christians must come to the text expectantly, believing it will speak to their own circumstances, and they must respond to it obediently.
