The Eucharist flows from the Passion of Christ. When we come to the Blessed Sacrament WE COME TO THE CROSS. During our Holy Hour we lift up to the Eucharistic Heart of Jesus those souls in most need of His mercy.
During our Holy Hour, those in most need of His mercy are stamped and marked with the Precious Blood of Jesus. This includes those who are to die that day. Stamped with the Precious Blood of Jesus, they are saved.

One night at San Miguel Church I had just finished my Holy Hour when a taxi drove up at 4am. A woman wanted me to talk with her son. They lived in Paranaque. She had been awakened by a voice telling her to come to the church of San Miguel. She got up just in time. Her son was about to commit suicide. He is now well and has been doing fine since his visit to San Miguel.

Another night, Nonette Silla was in the chapel praying from 2am to 3am the hour before mine. Three weeks before, she had lifted up to the Heart of Jesus a man she knew who was destroying the moral life of many of her girlfriends. Her prayer included this man because she knew that Jesus loved him too. Her prayer ended with an exclamation point that she wanted Jesus to bring him to the chapel so that she would know for sure that he was converted. Three weeks later, while she was in prayer at the chapel she heard someone sobbing in the back. She turned around, and it was him. He explained that for three weeks his mind was confused. What he thought was right now looked like it was wrong. He could not sleep. That night he began to drive around the city. He lived in Makati. When he passed the church of San Miguel, he saw the light on in the chapel. The light was inviting, welcoming. He decided to stop and come in.  What he met was not condemnation for his sins, instead he experienced tender mercy from the Blessed Sacrament. That is why he wept.

When I came in at 3am he told me his story. I heard his confession, gave him absolution, and he has been a daily communicant ever since. Nonette's Holy Hour stamped his soul with the Precious Blood of Jesus and he could not escape God's mercy and grace.

I did not see the movie "Schindler's List", but a friend told me about one touching scene. Schindler removes a gold pin from his lapel and cries that if he had sold that pin, he could have bought one more life, saved one more life. He weeps. He laments that he could have done more.
If only we knew the value of a Holy Hour we would never miss a single day without making one.

The Holy Father (Pope John 11) says in Dominicae Cenae that adoration makes "reparation" for the evils of the world. Because the Cross is infinite in merit, there is no limit to the value of a Holy Hour.

That is why Fr. John Hardon, S.J. says that it is absolutely impossible to exaggerate the value of a single Holy Hour of prayer in the Presence of Jesus in the Blessed Sacrament.

Jesus said: "And when I am lifted up from the earth, I will draw everyone to Myself". (Jn 12:32)

With each Holy Hour we draw down upon the parish and the world the graces He won for us on Calvary. The triumph of the Cross is the mercy we obtain from the Blessed Sacrament to stamp each and everyone with the Precious Blood of Jesus.
