Christians are likely to be unaware of the profound depths of their identity and sublime destiny. By Baptism, the Christian has become the temple of the indwelling Holy Spirit, so as to share in Christ's sonship of the Father. The new child of the Father is to become a new Christ: “We are no longer two people, Jesus and I; we are just one: Jesus alone” (Blessed Dina Bélanger). Part I begins with the need to experience the love of the Father and the friendship of Christ so as to attain a “mystical incarnation” through the Holy Spirit. Part II depicts the growth into Christ at His human and divine levels and our generation through two mothers (Church and Mary) and the Eucharist. Part III presents four dispositions in the heart of Christ: human virtues; peace of heart and abandonment in the present moment; joy; and the spirituality of communion.
