Turn to any page of St. Faustina's Diary, and you'll find spiritual gems. Like this one:

When I see that the burden is beyond my strength, I do not consider or analyze it or probe into it, but I run like a child to the Heart of Jesus and say … “You can do all things.” … I keep silent, because I know that Jesus Himself will intervene in the matter, and … instead of tormenting myself, I use that time to love Him. (1033)
