Catechism of the Catholic Church

2656 One enters into prayer as one enters into liturgy: by the narrow gate of faith. Through the signs of his presence, it is the Face of the Lord that we seek and desire; it is his Word that we want to hear and keep.

2657 The Holy Spirit, who instructs us to celebrate the liturgy in expectation of Christ's return, teaches us-to pray in hope. Conversely, the prayer of the Church and personal prayer nourish hope in us. The psalms especially, with their concrete and varied language, teach us to fix our hope in God: "I waited patiently for the LORD; he inclined to me and heard my cry." ⁸ As St. Paul prayed: "May the God of hope fill you with all joy and peace in believing, so that by the power of the Holy Spirit you may abound in hope." ⁹

2658 "Hope does not disappoint us, because God's love has been poured into our hearts by the Holy Spirit who has been given to us." ¹⁰ Prayer, formed by the liturgical life, draws everything into the love by which we are loved in Christ and which enables us to respond to him by loving as he has loved us. Love is the source of prayer; whoever draws from it reaches the summit of prayer. In the words of the Cure of Ars:

l love you, O my God, and my only desire is to love you until the last breath of my life. I love you, O my infinitely lovable God, and I would rather die loving you, than live without loving you. I love you, Lord, and the only grace I ask is to love you eternally.... My God, if my tongue cannot say in every moment that I love you, I want my heart to repeat it to you as often as I draw breath. ¹¹
