“Who hopeth in Gods helpe, his helpe can not starte:
Nothing is impossible to a willyng hart,
And will maie wyn my herte, herein to consent,
To take all thinges as it cometh, and be content.”

As quoted in Life of Pius X (1918) by Francis Alice Forbes, p. 35
Variant translation: My hope is in Christ, who strengthens the weakest by His Divine help. I can do all in Him who strengthens me. His Power is infinite, and if I lean on him, it will be mine. His Wisdom is infinite, and if I look to Him counsel, I shall not be deceived. His Goodness is infinite, and if my trust is stayed in Him, I shall not be abandoned.
Context: I shall spare myself neither care nor labour nor vigils for the salvation of souls. My hope is in Christ, who strengthens the weakest by His divine help; I can do all in Him who strengthened me! His power is infinite, and if I lean on Him it will be mine; His wisdom is infinite, and if I look to Him for counsel I shall not be deceived; His goodness is infinite, and if my trust is stayed on Him I shall not be abandoned. Hope unites me to my God and Him to me. Although I know I am not sufficient for the burden, my strength is in Him. For the salvation of others I must bear weariness, face dangers, suffer offences, confront storms, fight against evil. He is my Hope.

The Sixteenth Revelation, Chapter 76
Context: The soul that willeth to be in rest when other man’s sin cometh to mind, he shall flee it as the pain of hell, seeking unto God for remedy, for help against it. For the beholding of other man’s sins, it maketh as it were a thick mist afore the eyes of the soul, and we cannot, for the time, see the fairness of God, but if we may behold them with contrition with him, with compassion on him, and with holy desire to God for him. For without this it harmeth and tempesteth and hindereth the soul that beholdeth them. For this I understood in the Shewing of Compassion.
