I am not certain this is correct, but this idea may come from the Suscipe (Offering of Oneself), a prayer by St. Ignatius Loyola.
Suscipe, Domine, universam meam libertatem. Accipe memoriam, intellectum, atque voluntatem omnem. Quidquid habeo vel possideo mihi largitus es; id tibi totum restituo, ac tuae prorsus voluntati trado gubernandum. Amorem tui solum cum gratia tua mihi dones, et dives sum satis, hec aliud quidquam ultra posco.
Take Lord, and receive all my liberty, my memory, my understanding, and my entire will – all that I have and call my own. You have given it all to me. To you, Lord, I return it. Everything is yours; do with it what you will. Give me only your love and your grace. That is enough
