Miller addresses the misconception that Christianity is a religion primarily for women, arguing instead that Jesus embodies the full spectrum of manliness, combining gentleness with strength, courage, and integrity. He emphasizes that true manhood includes qualities such as moral courage, self-control, and love, which are exemplified in the life of Christ. Miller asserts that Jesus is the perfect model of humanity, showcasing both the tender and the heroic aspects of character. He challenges the world's standards of manliness, presenting Christ's teachings as the true guide for developing noble manhood. Ultimately, Miller encourages men to strive for Christlike qualities, recognizing that true manliness is a continual struggle supported by Christ as a helper and guide.
