77 Our relationship with the heart of Christ is thus changed, thanks to the prompting of the Spirit who guides us to the Father, the source of life and the ultimate wellspring of grace. Christ does not expect us simply to remain in him. His love is “the revelation of the Father’s mercy”, and his desire is that, impelled by the Spirit welling up from his heart, we should ascend to the Father “with him and in him”. We give glory to the Father “through” Christ, “with” Christ, and “in” Christ. Saint John Paul II taught that, “the Saviour’s heart invites us to return to the Father’s love, which is the source of every authentic love”. This is precisely what the Holy Spirit, who comes to us through the heart of Christ, seeks to nurture in our hearts. For this reason, the liturgy, through the enlivening work of the Spirit, always addresses the Father from the risen heart of Christ.
