The sermon centers on the transformative call to 'walk in the way of Christ,' emphasizing that true Christian discipleship is not merely external conformity to moral rules but an internal renewal of the heart through personal relationship with Christ. Drawing from Ephesians 4:20–24, it argues that genuine faith begins with hearing and embracing Christ personally—not just receiving doctrinal information—highlighting that salvation involves a heart change initiated by God, as promised in the Old Testament and fulfilled in Christ. The preacher underscores that authentic discipleship begins by learning Christ, which involves having heard Christ and being taught in Him. The message challenges believers to examine whether their lives reflect a deep, personal relationship with Christ or merely outward religious habits, calling for a wholehearted commitment to know, follow, and be shaped by Christ alone.
