126 Some of the language of Saint Margaret Mary, if poorly understood, might suggest undue trust in our personal sacrifices and offerings. Saint Claude insists that contemplation of the heart of Jesus, when authentic, does not provoke self-complacency or a vain confidence in our own experiences or human efforts, but rather an ineffable abandonment in Christ that fills our life with peace, security and decision. He expressed this absolute confidence most eloquently in a celebrated prayer: “My God, I am so convinced that you keep watch over those who hope in you, and that we can want for nothing when we look for all in you, that I am resolved in the future to live free from every care and to turn all my anxieties over to you... I shall never lose my hope. I shall keep it to the last moment of my life; and at that moment all the demons in hell will strive to tear it from me… Others may look for happiness from their wealth or their talents; others may rest on the innocence of their life, or the severity of their penance, or the amount of their alms, or the fervour of their prayers. As for me, Lord, all my confidence is confidence itself. This confidence has never deceived anyone… I am sure, therefore, that I shall be eternally happy, since I firmly hope to be, and because it is from you, O God, that I hope for it”.
