prayer before communion

O my God, I firmly believe that you are truly present in the Holy Eucharist. I confess that I am a poor sinner and am not worthy to receive you. But you just say a word and my soul shall be healed, and then I can receive you into my soul. I am sorry for all my sins because they have offended you and I resolve never to commit them again. Lord, have mercy and forgive me. I desire with my whole heart to receive you. Come into my heart and make it your abode. Amen
