A.W. Tozer emphasizes that true spirituality is often misunderstood, as many perceive spiritual Christians to be timid and gentle, while the Bible presents a different picture. He categorizes Christians into four groups: unconverted attendees, false Christians, carnal Christians, and spiritual Christians, highlighting that carnal Christians exhibit traits of immaturity similar to babies, such as self-centeredness and being overly influenced by their senses. Tozer urges believers to grow beyond these characteristics by seeking spiritual maturity through discipline, purpose, and a deeper relationship with God. He calls for Christians to move away from external influences and trivial pursuits, advocating for a life of purpose and a comprehensive engagement with Scripture. Ultimately, Tozer encourages the congregation to strive for spiritual growth and maturity in their faith.

Horatius Bonar emphasizes that a Christian is fundamentally a reflection of Christ, embodying His faith, prayer, hope, holiness, love, and zeal. He asserts that true Christians should not merely imitate other figures like Paul or Luther, but strive to follow Christ's example in every aspect of their lives. Bonar outlines that a Christian's life is characterized by unwavering faith, constant prayer, hopeful anticipation of glory, a commitment to holiness, a life of love, and fervent zeal for God's work. He encourages believers to grow in these attributes, ensuring they are not stagnant but continually transformed into Christ's likeness. Ultimately, Bonar calls for a deep, active faith that manifests in every action and thought.
