Now is the time to pray to Pentecost Novena. What is a novena? Why should we pray it?
Here's an explanation from The Church's Most Powerful Novenas by Michael Dubruiel (part 2)
2. Praying a novena reinforces a sense that God is our Father and that God loves us. Well-meaning people have done a very good job of spreading a false gospel that good Christians shouldn't ask God for anything, that we shouldn't be seeking favors from the Father. This is sad and clearly not in keeping with the teaching of the Gospel, where Jesus asks, "What do you want me to do for you?" (Mk. 10:51).
In the Spiritual Exercises of St. Ignatius of Loyola, the founder of the Jesuits instructed his retreatants to begin every period of prayer by imploring God for a particular grace that they wished to receive as a result of the prayer. At the very end of his Exercises, Ignatius then instructs them to make what he calls a "Contemplation to Attain Divine Love."
This reflection is made by contemplating how lovers enjoy giving gifts to their beloved and how, if God loves us, certainly he must also give us gifts. Retreatants consider what gifts God has given to them, personally, in their lifetime. Just as making a retreat can bring us to this appreciation of God's love, so praying intently for nine days can deepen our consciousness of, and trust in, God's care.
