Ask Saint Paul the Apostle to pray for you:
Great convert and Apostle of the Gentiles, you became Christlike and knew only Christ Crucified. Though extremely learned, you relied completely on the Wisdom received from the Spirit and taught from the abundance of your heart. Instruct modern evangelists - those who preach Christ to others. Let them realize that their actions speak louder than any words they may use. Teach them to use their talents in conveying their God-given message but to rely above all on the promptings of the Spirit. Amen.
