There are 13 paragraphs in the Catechism of the Catholic Church that discuss surrender to God:
931 Already dedicated to him through Baptism, the person who surrenders himself to the God he loves above all else thereby consecrates himself more intimately to God's service and to the good of the Church. By this state of life consecrated to God, the Church manifests Christ and shows us how the Holy Spirit acts so wonderfully in her.
945 Already destined for him through Baptism, the person who surrenders himself to the God he loves above all else thereby consecrates himself more intimately to God's service and to the good of the whole Church.
1078 Blessing is a divine and life-giving action, the source of which is the Father; his blessing is both word and gift. When applied to man, the word "blessing" means adoration and surrender to his Creator in thanksgiving.
921 They manifest to everyone the interior aspect of the mystery of the Church, that is, personal intimacy with Christ. Hidden from the eyes of men, the life of the hermit is a silent preaching of the Lord, to whom he has surrendered his life simply because he is everything to him. Here is a particular call to find in the desert, in the thick of spiritual battle, the glory of the Crucified One.
2712 Contemplative prayer is the prayer of the child of God, of the forgiven sinner who agrees to welcome the love by which he is loved and who wants to respond to it by loving even more. But he knows that the love he is returning is poured out by the Spirit in his heart, for everything is grace from God. Contemplative prayer is the poor and humble surrender to the loving will of the Father in ever deeper union with his beloved Son.
2825 "Although he was a Son, [Jesus] learned obedience through what he suffered." How much more reason have we sinful creatures to learn obedience - we who in him have become children of adoption. We ask our Father to unite our will to his Son's, in order to fulfill his will, his plan of salvation for the life of the world. We are radically incapable of this, but united with Jesus and with the power of his Holy Spirit, we can surrender our will to him and decide to choose what his Son has always chosen: to do what is pleasing to the Father. In committing ourselves to [Christ], we can become one spirit with him, and thereby accomplish his will, in such wise that it will be perfect on earth as it is in heaven.
2830 "Our bread": The Father who gives us life cannot but give us the nourishment life requires – all appropriate goods and blessings, both material and spiritual. In the Sermon on the Mount, Jesus insists on the filial trust that cooperates with our Father's providence. He is not inviting us to idleness, but wants to relieve us from nagging worry and preoccupation. Such is the filial surrender of the children of God: To those who seek the kingdom of God and his righteousness, he has promised to give all else besides. Since everything indeed belongs to God, he who possesses God wants for nothing, if he himself is not found wanting before God.
37 For the truths that concern the relations between God and man wholly transcend the visible order of things, and, if they are translated into human action and influence it, they call for self-surrender and abnegation. (Pius XII)
305 Jesus asks for childlike abandonment to the providence of our heavenly Father who takes care of his children's smallest needs: "Therefore do not be anxious, saying, "What shall we eat?" or "What shall we drink?". . . Your heavenly Father knows that you need them all. But seek first his kingdom and his righteousness, and all these things shall be yours as well."
2554 The baptized person combats envy through good-will, humility, and abandonment to the providence of God.
2547 Abandonment to the providence of the Father in heaven frees us from anxiety about tomorrow. Trust in God is a preparation for the blessedness of the poor. They shall see God.
215 "The sum of your word is truth; and every one of your righteous ordinances endures forever." "And now, O LORD God, you are God, and your words are true"; this is why God's promises always come true. God is Truth itself, whose words cannot deceive. This is why one can abandon oneself in full trust to the truth and faithfulness of his word in all things. The beginning of sin and of man's fall was due to a lie of the tempter who induced doubt of God's word, kindness and faithfulness.
2677 Holy Mary, Mother of God: With Elizabeth we marvel, "And why is this granted me, that the mother of my Lord should come to me?" Because she gives us Jesus, her son, Mary is Mother of God and our mother; we can entrust all our cares and petitions to her: she prays for us as she prayed for herself: "Let it be to me according to your word." By entrusting ourselves to her prayer, we abandon ourselves to the will of God together with her: "Thy will be done."
Pray for us sinners, now and at the hour of our death: By asking Mary to pray for us, we acknowledge ourselves to be poor sinners and we address ourselves to the "Mother of Mercy," the All-Holy One. We give ourselves over to her now, in the Today of our lives. And our trust broadens further, already at the present moment, to surrender "the hour of our death" wholly to her care. May she be there as she was at her son's death on the cross. May she welcome us as our mother at the hour of our passing to lead us to her son, Jesus, in paradise.
