THE SACRED HEART OF JESUS . . . began this devotion of the Holy Hour of Reparation, when He entered the Garden of Gethsemane on Mount Olivet. He said to His Apostles: "My soul is sorrowful even unto death. Stay ye here and watch with Me." Later He said to them: "Could ye not watch one hour with Me? Watch and pray, that ye enter not into temptation." [Matt. 26:38, 40, 41]
As Jesus spoke to His Apostles, so He pleads with us to stay and watch and pray with Him. His Sacred Heart is filled with sadness, because so many doubt Him, despise Him, insult Him, ridicule Him, spit upon Him, slap Him, accuse Him, condemn Him. In the Sacrament of His Love, so many forget Him. Every mortal sin brings down the terrible scourges on His Sacred Body, presses the sharp thorns into His Sacred Head, and hammers the cruel nails into His Sacred Hands and Feet.
The ingratitude of mankind continually pierces His Sacred Heart.
When Jesus saw the sins of the world and the reparation that must be made to His Heavenly Father, He began to fear and to be sad and sorrowful. "Kneeling down, He prayed: 'Father, if Thou will, remove this chalice from Me; But not My Will, Thine be done: There appeared an Angel from Heaven to strengthen Him; and being in agony, He prayed the longer, and His sweat became as drops of blood trickling to the ground." [Luke 22:41, 44]
The Sacred Heart of Jesus said to St. Margaret Mary: "Make reparation for the ingratitude of men. Spend an hour in prayer to appease Divine justice, to implore mercy for sinners, to honor Me, to console Me for My bitter suffering when abandoned by My Apostles, when they did not WATCH ONE HOUR WITH ME."
"That the necessity of Expiation and Reparation is especially urgent today must be evident to everyone who considers the present plight of the world, 'seated in wickedness' [John 5:9]. The Sacred Heart promised to St. Margaret Mary that he would reward abundantly with His graces all those who should render this honor to His Heart."
