I will love thee, O LORD, my strength. The LORD is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower.

Today Jesus said to me, I desire that you know more profoundly the love that burns in My Heart for souls, and you will understand this when you meditate upon My Passion.

“O Blood and Water, which gushed forth from the Heart of Jesus as fount of Mercy for us, I trust in You.” (Diary, 187)
