Dr. McKay concludes the book of Ephesians by unpacking Paul’s teaching on spiritual warfare, reminding believers that the real battle is not against people or institutions but against spiritual forces of evil. He explains that Paul’s command is not to attack but to stand firm—to rest securely in the believer’s identity in Christ. The armor of God symbolizes this defense: truth, righteousness, faith, salvation, and the Word of God all flow from being “in Christ.” Prayer and Scripture are presented as the believer’s active stance against deception and fear.

Turning to Philippians, Dr. McKay emphasizes Paul’s tone of gratitude and joy despite imprisonment. At the center of the letter stands the profound “Christ Hymn” of Philippians 2:5–11, which describes Jesus’ humility in becoming human, serving, and dying on a cross, followed by his exaltation to the highest place. This early Christian confession demonstrates that the church from its earliest days worshiped Jesus as both fully God and fully man. Paul’s point: true greatness in God’s kingdom comes through humility.

In Colossians, Dr. McKay connects Paul’s response to false teaching with the supremacy of Christ. The Colossian hymn (1:15–20) celebrates Jesus as the image of the invisible God, the creator and sustainer of all things, and the firstborn from the dead—the beginning of the new creation. Against mystical philosophies and angelic visions, Paul insists that Christ alone is sufficient, supreme, and preeminent in creation and in the Church.

Together, these prison letters call believers to stand firm in Christ’s victory, follow his humility, and recognize his unrivaled Lordship over all things in heaven and on earth.
