Through faith in Christ the child of earth is made an heir of God, joint-heir with Jesus Christ. Those who behold Jesus become changed to his image, become assimilated to his nature; and the glory of God that shines in the face of Jesus, is reflected in the lives of his followers. More and more the Christian is changed from glory to glory as by the Spirit of the Lord, and he becomes the light of the world. The more he looks on Christ, the more he loves and longs to look again; and the more light and love and glory he sees in Christ, the more his light increases unto the perfect day. "We all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord."

Gennem troen på Kristus er jordens barn gjort til Guds arvinger; Kristi medarvinger. De, der betragter Jesus, bliver forvandlede til hans billede, bliver ét med hans natur og Guds herlighed, som stråler i Jesu ansigt, genspejles i hans efterfølgeres liv, Den kristne forandres mere og mere fra herlighed til herlighed . Jo mere han betragter Kristus, des mere elsker han og længes efter at se ham igen og jo mere lys og herlighed han ser i Kristus, des mere forøges hans eget lys bliver større til den fuldkomne dag. "Og alle vi, som med utildækket ansigt skuer Herrens herlighed i et spejl, forvandles til det samme billede, fra herlighed til herlighed, eftersom det kommer fra Åndens Herre."
