Discovery of the work
It was a Lutheran inter-denominational women's Bible study leader who shared this work with me.
Impact on love for the Gospel
These Revelations to Maria Valtorta greatly accelerated my journey into the Catholic Church, and my transition from being a former fundamentalist Baptist pastor to a Catholic apologist would hardly have been possible without it
Concrete impact on faith life
All throughout the work, I was absolutely overwhelmed by the Love, Patience, and Self-Sacrifice of the Lord. I have told others that if you decide to read this work, you had better have a full box of Kleenex near you. These divine revelations not only establish the truth of the Catholic Faith but (or because they do!) do not at all overlook the serious decline of true Catholic faith in both the laity and the priesthood during WWII, and especially in the time that would follow: "a brief time in which the enemy would regroup for an ever greater assault." The honesty was quite assuring to me.
What would you say to someone who hesitates to discover this work?
If you care to actually feel as though you have lived with Jesus and His Disciples for those three-and-a-half years, and to be impacted as the Apostles were on the Day of Pentecost, this work is clearly for you!
Additional testimony
These Revelations also fully resolved several what were thought to be contradictions between the Gospel writers. Here it was revealed that only missing information had led to false conclusions, and with the information restored, the alleged contradiction vanishes. It has also been revealed that these Revelations (the only "so-called" private Revelation ever ordered by a pope to be published in the entire history of the Church!) will play a very predominate role in the coming New Evangelization at the Triumph of Mary! It seems very obvious, then, that the attempt at the New Evangelization at Vatican II failed because these revelations were severely repressed, and thus the Holy Spirit was missing at the Council! Could there then be anything with a greater priority than the promotion of these Revelations?
