Prayer For The Grace To Become A Priest

O Lord Jesus Christ, great High Priest, who calls chosen individuals to present themselves in sacrifice and to assist in the salvation of souls, I implore You to bestow upon me this noble grace, although I feel completely unworthy. Help me to prepare my heart diligently to accept it and to maintain my purity and humility so that You might summon me to serve at Your altar. Amen. O Mary, Mother of God and my beloved mother, please intercede for me to your Son's Sacred Heart that I may receive this grace.
