There are 3 different prayers that are said for 9 days each as a novena. The prayers below are miraculous as attested by the faithful who visit the shrine of St Lawrence in Attur, Karkala which is placed in the south-indian state of Karnataka, India.
Glorious Martyr, St. Lawrence, we come to you in humility as we see your greatness and your power of intercession with God. You were so strong in your faith that you readily suffered tortures from the pagans and died a cruel death becoming an outstanding witness to Christ and His Church. As we discern your strong faith we believe in your powerful patronage and pray you to obtain for us a living faith, an unwavering hope and love of God and of our neighbour. Keep us pure and chaste; make us obedient to our elders. Help us to help the poor, the down trodden, the sick and those in trials and difficulties. Touch the tepid Christians and enkindle in them the fire of faith, and give the non-Christians the grace of faith in Christ. As the pagans were moved to your faith in Christ so may your immortal faith make the unbelievers embrace the true faith that the Kingdom of God may flourish. Assist us always to overcome our trials and temptations. Grant that we may always live a true Christian life and finally be victorious in the battle of faith that being true witnesses to Christ we may die in Him to join you and other saints and live for all eternity in His Kingdom to praise God for ever and ever. Amen
O St. Lawrence, who in the flower of youth suffered and died for the faith, hear our prayers. With confidence we fly to your patronage. Obtain for us deep faith, strong hope, a sincere love of God and neighbour, unsullied chastity and humble obedience. Inspire us to succour the poor, the needy, the sick and the afflicted. Lead the erring back to the Father's Home. May God's Kingdom spread far and wide on earth. Help us in all our needs especially............. Finally grant that we live as the worthy people of God, die a holy death and join you in the heavenly bliss for ever. Amen.
O holy St Lawrence, Apostle and Martyr, great in virtue and rich in miracles, near kinsman of Jesus Christ, faithful intercessor of all who invoke your special patronage in time of need to you, I have recourse from the depth of my heart and humbly beg to whom God has given such great power to come to my assistance. Help me in my present urgent petition. In return I promise to make your name known and cause you to be invoked.
(Say 3 Our Fathers, 3 Hail Mary and 3 Glories)
St Lawrence pray for us and all who invoke your aid. Amen
