CCC 368 The spiritual tradition of the Church also emphasizes the heart, in the biblical sense of the depths of one’s being, where the person decides for or against God.1

CCC 733 “God is Love”2 and love is his first gift, containing all others. “God’s love has been poured into our hearts through the Holy Spirit who has been given to us.”3

CCC 1820 Christian hope unfolds from the beginning of Jesus’ preaching in the proclamation of the beatitudes. The beatitudes raise our hope toward heaven as the new Promised Land; they trace the path that leads through the trials that await the disciples of Jesus. But through the merits of Jesus Christ and of his Passion, God keeps us in the “hope that does not disappoint.”4 Hope is the “sure and steadfast anchor of the soul. .. that enters. .. where Jesus has gone as a forerunner on our behalf.”5 Hope is also a weapon that protects us in the struggle of salvation: “Let us. .. put on the breastplate of faith and charity, and for a helmet the hope of salvation.”6 It affords us joy even under trial: “Rejoice in your hope, be patient in tribulation.”7 Hope is expressed and nourished in prayer, especially in the Our Father, the summary of everything that hope leads us to desire.

CCC 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.”8 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.9

CCC 2734 Filial trust is tested – it proves itself – in tribulation.10 The principal difficulty concerns the prayer of petition, for oneself or for others in intercession. Some even stop praying because they think their petition is not heard. Here two questions should be asked: Why do we think our petition has not been heard? How is our prayer heard, how is it “efficacious”?

CCC 2847 The Holy Spirit makes us discern between trials, which are necessary for the growth of the inner man,11 and temptation, which leads to sin and death.12 We must also discern between being tempted and consenting to temptation. Finally, discernment unmasks the lie of temptation, whose object appears to be good, a “delight to the eyes” and desirable,13 when in reality its fruit is death.
God does not want to impose the good, but wants free beings. .. There is a certain usefulness to temptation. No one but God knows what our soul has received from him, not even we ourselves. But temptation reveals it in order to teach us to know ourselves, and in this way we discover our evil inclinations and are obliged to give thanks for the goods that temptation has revealed to us.14
