The sermon centers on identifying the true child of God through the twin marks of genuine faith and new birth, as revealed in John 1:11–13. It emphasizes that true faith is not mere intellectual assent or religious performance, but a personal, trusting reception of Christ alone as the sole object of salvation, rejecting self-reliance, cultural religion, and false spiritualities rooted in autonomy or relativism. New birth, the divine work of God, is not derived from lineage, human effort, or the influence of others, but is a sovereign act of God that transforms the heart, evidenced by a renewed love for God, a hatred of sin, and a longing for His Word. The message calls believers to examine their lives not by the quality of their faith, but by the reality of their relationship with Christ, urging them to rest in His finished work, avoid self-deception, and live in joyful obedience and assurance as adopted children of God.
