Whenever I want to pray for something very important I use a form of prayer called the Triple Colloquy given to the Church by St. Ignatius of Loyola. In his words, "The Colloquy is made, properly speaking, as one friend speaks to another, or as a servant to his master; now asking some grace, now blaming oneself for some misdeed, now communicating one's affairs, and asking advice in them." After I have clarified what I am seeking from God, here is what I do:
1. I first speak to the Blessed Mother: "Dear Mary, please take my request to your Divine Son, that He may present this request to our Heavenly Father."
Then I pray the Hail Mary.
2. Then I ask the Lord Jesus: "Lord Jesus, I beg you to take this request and present it to Your Father."
Then I pray the Anima Christi* (Latin for “Soul of Christ”)
3. Then I speak to the Father: "Abba Father, with Your Son interceding for me, and with Mary our Queen, standing here on my behalf, please grant my request.”
I conclude with praying the Our Father.
*Soul of Christ, sanctify me
Body of Christ, save me
Blood of Christ, inebriate me
Water from the side of Christ, wash me
O good Jesus, hear me
Within your wounds, hide me
Permit me not to be separated from you
From the wicked enemy, defend me
At the hour of my death, call me
And bid me come to you
That with your saints I may praise you
For ever and ever.
