In 'Spiritual Disciplines for the Christian Life,' Donald S. Whitney emphasizes the critical importance of prayer and Bible study as foundational practices for Christians, supported by biblical commands. Surveys reveal that many Christians and pastors pray only briefly each day, highlighting a significant gap in prayer discipline and devotion. Whitney encourages believers to view prayer as an opportunity for relationship with God rather than an obligation, while also acknowledging that prayerlessness can stem from various challenges, including lack of discipline and spiritual awareness.
