This is a beautiful prayer to the Holy Spirit that I found at In God's Company 2. It comes from Fr. Jozo of Medjugorje:
Fr. Jozo's Prayer to the Holy Spirit in Siroki Brijeg October 3, 2000
Come, O Most Holy Spirit, come to us today. We need your love, because we desire to go on the new way to return to the Father, to take the step to the Father. O Come, Holy Spirit, You who makes all things new. Today grant a miracle in us and through us. Change our hearts. Take from us our hearts of stone and give us a new heart, a heart that knows how to love, how to pray, how to forgive. A heart that knows how to embrace the cross and recognize the will of God and carry it to the end. Come, O Most Holy Spirit, You who are our peace, come fill us with peace. You who are love, fill us with love and blessing and salvation. We are not here accidentally. We have been called, that we may be able to recognize our call and our mission. We ask You to come O Most Holy Spirit, that our masks may melt away, that our true face may be revealed before You. Come, O Most Holy Spirit, may a miracle happen today: the beginning of our conversion, the beginning of our true devotion. Come, O Most Holy Spirit pour out Your grace and Your strength on Your Church and convert us. Sanctify us. Change us. Come, O Most Holy Spirit, we are the Church united together in prayer with the Mother. As the disciples at the very beginning, united together with Her in prayer for the gift of Your Spirit, for the gift of love, that we may be freed from selfishness and hatred, that we may be freed from every evil, and that we may start to love, that we may start to forgive and to pray, that we may start to fast. Come, O Most Holy Spirit. Come bless us. Come, change us. You who are prayer, come and anoint us with prayer that we may become the Church that believes in the power of prayer. Come, Most Holy Spirit, renew prayer in us, that we may become the renewers of family prayer.Come, O Most Holy Spirit, come heal us, come bless us, come convert us. O You who anoints with Your Peace, with Your Joy, with Your Love. Come anoint us.
In the last message O Blessed Mother, You say, that the one who prays, lives joy and peace and love. O Blessed Mother, here is the Church in prayer, here is the Church who desires to renew itself in prayer, firm in prayer, come to fall in love with prayer. O grant that these days may be the renewal of our prayer, of our faith through prayer, of our love through prayer, of a Christian life in prayer. Come, O Most Holy Spirit. Come, pour Yourself out upon us. The Church united together with the Mother is praying to you, You who make all things new. Grant that this Church may become new. It may become a Church of prayer, a holy Church, a sign amongst nations, your city on the hillside, your light on the way, Your Self. Come, O Most Holy Spirit. Come and pour Yourself out upon us. Our Father who art in Heaven....Hail Mary, full of grace...Mother and Queen of Peace - pray for us. Mother of the Church - pray for us. Mother and Queen of the family - pray for us. Consolation of the Sorrowful - pray for us, help of Christians - pray for us, help of the sick - pray for us, gate of heaven - pray for us. In the name of the Father and of the Son and of the Holy Spirit, Amen.
