At twelve, Jesus sits among temple teachers, listening, asking questions and growing in wisdom. Though He is God's eternal Son, He develops slowly within a family and faith community, in body, relationships and faithful obedience to His Father. His ordinary growth shows why generations belong together. The boy in the temple becomes the man on the cross, completing the mission that saves people and brings every generation together on equal ground. Church life should welcome children's questions, honour older wisdom and trust God with slow growth.
