A.W. Tozer emphasizes the necessity of total commitment to Jesus Christ, asserting that He must be central, basic, and preeminent in the life of every believer. Tozer explains that true commitment involves an intellectual understanding of Christ, a volitional choice to follow Him, and an exclusive attachment that rejects anything contrary to His teachings. He warns against the dangers of adding anything to Christ, insisting that He is sufficient on His own. The preacher calls for a deep, irrevocable commitment to Christ, likening it to a soldier's dedication in battle, where there is no turning back. Ultimately, Tozer encourages believers to embrace their identity in Christ and live out their faith with unwavering devotion.

A.B. Simpson emphasizes the duality of human insufficiency and Christ's all-sufficiency, asserting that recognizing our helplessness is essential for spiritual growth. He explains that the Old Testament highlights human failure, while the New Testament reveals Christ's ability to meet all our needs. Simpson encourages believers to renounce their own perceived perfection and embrace Christ's righteousness, which leads to a deeper understanding of grace. He warns that acknowledging our insufficiency must be coupled with a firm faith that claims all that Christ offers. The sermon concludes with a call to humility and a full acceptance of God's greatness and grace.
